ATOMIC Redster TR 3

The ATOMIC Redster TR 3 is a race ski boot for performance-oriented, technically advanced and competitive skiers who demand highly precise ski control, rapid response and direct power transmission without necessarily needing the extreme stiffness of the hardest race boots. With an exact flex of 110 and an exceptionally narrow 93 mm Racing Last, this is a specialized boot where precision and secure foot retention clearly take priority over a spacious, comfort-oriented fit.

The model makes particular sense for ambitious young racers, lighter competitive skiers and technically accomplished skiers who can take advantage of a true race fit. The combination of a PU shell, PP cuff, 93 mm Racing Last and World Cup Race Liner creates a very close connection between the foot and the boot, supporting immediate response during edge changes and precise pressure control through the skis.

The Redster TR 3 also provides extensive options for adjusting race stance and fit. Its construction incorporates Dual-Sided Cuff Alignment, Power Control, Redster AFS Tongue, Ankle Retention System, full liner lacing and a 55 mm Professional Dual Strap. It is therefore a technically sophisticated race platform for skiers who understand what to expect from a precisely fitted race boot and are prepared to pay close attention to professional bootfitting.

Who are these ski boots for?

According to the official product classification, the ATOMIC Redster TR 3 is a men’s/unisex Race ski boot designed for competitive skiers. Its exact flex of 110 places it in an interesting position for skiers who require a high degree of support and precision without needing the extreme stiffness of the most demanding race shells.

The model is particularly suitable for skiers who:

• compete or have highly developed skiing technique
• are looking for a genuinely narrow race fit with a 93 mm last
• prioritize precision and rapid response over maximum all-day comfort
• want flex 110 as a combination of race-oriented support and somewhat more accessible flexing
• have narrow feet or are prepared to achieve the correct fit through professional bootfitting
• require secure heel and ankle retention
• want a race-oriented liner with full lacing
• will benefit from cuff and stance adjustment options
• are looking for a substantial 55 mm Professional Dual Strap
• need a boot focused on highly precise transmission of movements to the skis

With a last measuring only 93 mm, correct sizing and professional assessment of the fit are particularly important. The Redster TR 3 is not a comfort-oriented High Volume model – its very close race fit is an intentional part of the design.

How do the boots perform on the slopes?

The Redster TR 3 is designed for a skier who actively works with pressure and expects an immediate response from the boot. Flex 110 provides substantial support under load, while potentially remaining more manageable for lighter racers and skiers who do not need the maximum stiffness offered by the hardest race boots.

The 93 mm Racing Last plays a fundamental role. Minimal space between the foot, liner and shell helps limit unwanted movement inside the boot and creates a very direct connection with the ski. This supports quicker turn initiation, more precise edge engagement and finer control over pressure throughout the turn.

Such a narrow construction does, however, require suitable foot anatomy and proper fitting. A 93 mm last is not automatically the right choice for a skier with wider feet simply because the model is race-oriented. Professional bootfitting is particularly appropriate for a ski boot in this category.

How to understand the parameters

Flex 110

The exact flex index of 110 provides a high level of support consistent with the performance and race focus of the boot. When flexed forward, the shell offers substantial resistance for active pressure management and supports precise ski control.

Within the world of race boots, however, flex 110 represents a more accessible option than extremely stiff racing models. It can therefore be particularly suitable for lighter racers or technically advanced skiers who want race-level precision but do not need the stiffest available shell.

Flex indices are not completely standardized between manufacturers. In addition to the stated value of 110, the skier’s body weight, strength, technical ability and intended use should therefore be considered.

93 mm Racing Last

The 93 mm width represents an extremely narrow racing last. Its primary purpose is not to provide generous interior space, but to create the most precise possible connection between the foot, boot and ski.

The close-fitting shape helps reduce unwanted foot movement inside the shell, supporting faster transmission of the skier’s movements and more precise edge control. This is exactly why this type of fit is characteristic of race-oriented ski boots.

At the same time, the internal volume is considerably lower than in conventional performance ski boots. With a shell this narrow, professional bootfitting can be an important part of achieving the correct final fit.

Race shell construction

The Redster TR 3 uses a PU Shell / PP Cuff, combining a polyurethane shell with a polypropylene cuff. The shell construction also incorporates several specific features: TR Wall Thickness, Power Chassis, Anatomic Toe Box, 0° Sole Canting, Grind Grid and Depth Guide Boot Board.

TR Wall Thickness refers to the wall-thickness construction used within the boot’s race-oriented shell design. The supplied information does not specify exact thicknesses or their distribution, so additional mechanical properties should not be assumed beyond its role within the race construction.

Power Chassis is a structural shell feature intended to contribute to the functional behavior of the boot under load and during power transmission. The exact mechanics are not specified in the supplied data, so it is best understood as part of the race-oriented shell structure.

Anatomic Toe Box refers to the anatomically shaped toe area. With an exceptionally narrow 93 mm racing last, appropriate shaping of individual shell areas contributes to the overall fit while retaining the deliberately narrow character of the boot.

0° Sole Canting is a specific geometric parameter of the sole construction, stated by the manufacturer at zero degrees.

Grind Grid is a feature associated with shell modification during bootfitting. With race boots, professional shell work can play an important role in achieving a precise individual fit.

Depth Guide Boot Board relates to the boot board and its modification. However, the supplied information does not specify adjustment ranges or modification limits, so these should not be inferred.

World Cup Race Liner

The liner is designated World Cup Race Liner and complements the race-oriented character of the Redster TR 3. Its construction is focused on precise foot retention and direct interaction with the race shell.

The World Cup designation in the liner name does not by itself establish certification or confirm use by specific World Cup athletes. It indicates the race-oriented positioning of this component within the product range.

Redster AFS Tongue and Ankle Retention System

The liner construction incorporates the Redster AFS Tongue, a specific tongue solution within the Redster system. The supplied technical data does not describe the exact adjustment mechanism, so specific ranges or methods of customization should not be assumed.

The Ankle Retention System is focused on securing the ankle area. Stable ankle and heel retention are particularly important in a race boot because reducing unwanted foot movement supports more precise transmission of the skier’s inputs to the skis.

The liner also features a Microfiber Outer and Full Lacing. Full lacing allows the liner to be secured directly around the foot and lower leg before the outer shell itself is closed.

A Dual Velcro Spoiler further complements the cuff area. The supplied information does not, however, specify its exact adjustment method or range.

Magnesium Elite Buckles

The closure system is specified as Magnesium Elite Buckless. This designation refers to the race-oriented buckle system and identifies magnesium within the supplied closure-system name.

The provided technical information does not specify the number of buckles or confirm particular micro-adjustment capabilities. These details should therefore not be added without further confirmation.

Dual-Sided Cuff Alignment and Power Control

The cuff technologies include Dual-Sided Cuff Alignment and Power Control.

Dual-Sided Cuff Alignment allows the cuff alignment to be adjusted from both sides, helping adapt its position more closely to the skier’s individual anatomy and stance. The exact adjustment range is not specified in the supplied information.

Power Control is another cuff-related feature associated with the functional behavior and support of the cuff under load. Since the supplied data does not provide the exact mechanism or adjustment range, it should not be associated with a specific flex change or other unsupported numerical values.

Adjustable cuff angle

The Redster TR 3 provides the stated cuff-angle settings of 16° as standard / 18° / 0°. This allows the geometry of the skier’s stance to be adjusted according to individual requirements and the overall setup of the boot.

In a race boot, changes in stance can have a significant influence on how the skier manages pressure and positioning over the skis. For this reason, such adjustments are best considered as part of the complete bootfitting process and the individual requirements of the racer.

55 mm Professional Dual Strap

The upper cuff is complemented by a substantial 55 mm Professional Dual Strap. Its 55 mm width provides a large contact area around the upper section of the boot and helps create a secure connection between the shin, tongue and cuff.

In a race-oriented boot, precise closure in this area is important for maintaining consistent contact while working with flex and pressure. The supplied information does not provide further details about the Dual Strap construction, so its exact mechanism should not be inferred.

Redster Solid Sole

The sole is specified as Redster Solid Sole, a solution consistent with the race-oriented character of the Redster TR 3.

The supplied information does not state a specific sole standard or GripWalk compatibility. Compatibility between the actual sole configuration of the specific pair and the intended ski binding should therefore be verified before use.

Redster TR 3: race precision with flex 110

The Redster TR 3 combines a 93 mm Racing Last with flex 110, creating a very specific performance profile. The exceptionally narrow shell delivers a close race fit, while flex 110 provides substantial support without requiring the skier to move to the stiffest race variants.

This combination can be particularly interesting for ambitious young racers, lighter competitive skiers and technically advanced skiers who want rapid response and precise edge control but would find a stiffer race shell unnecessarily demanding.

The model is available in sizes 24/24.5–28/28.5 and the Red Tension/Black/Magenta colorway. The manufacturer specifies a weight of 2.317 kg in size 26–26.5, without further clarification as to whether this figure refers to one boot. The manufacturer code is AE5031720 and the product code is N25001236.

Why choose the ATOMIC Redster TR 3?

The ATOMIC Redster TR 3 is designed for skiers who value precision, secure foot retention and rapid response more highly than generous comfort-oriented space. The exceptionally narrow 93 mm Racing Last provides the foundation for a direct connection with the skis, while flex 110 delivers race-oriented support in a somewhat more accessible form than the stiffest race models.

The PU shell with PP cuff, World Cup Race Liner with full lacing, Ankle Retention System, cuff adjustment options, Magnesium Elite Buckles and wide 55 mm Professional Dual Strap create a technically sophisticated package for ambitious racers and highly advanced skiers capable of taking advantage of a genuinely narrow race boot. The Redster TR 3 is not a universal comfort boot for every skier – its purpose is to deliver race-oriented precision, control and detailed adjustment options for skiers who specifically demand these characteristics.
