Why do I need to enter my weight? What is the VKTRY Pro Level?
VKs come in 5 different Pro Levels. This is the flexibility of the insoles… the strength of the “Spring”. The bigger the athlete, the more spring he or she will need, the higher the Pro Level. VKTRY uses an algorithm to determine the best Pro Level for the athlete so that the insoles deliver the best combination of performance, protection and comfort.
