The ski boots are numbered in two sizes. Each pair of numbers has the same size of skeleton and inner shoe. If a smaller size is required, you place the enclosed sole (lifter) between the inner shoe and the skeleton or between the original orthopedic insole and the inner shoe. Inserting the lifter reduces the space in the boot, so if you have a pair of numbers 26 / 26.5 you get a size 26.
