Zamst Footcraft Series Insoles 3L (29.0-30.5cm), Shock Absorbing, Standard Type, Arch Type HIGH, Unisex

---------------------------------------------------------------------- ZAMST's sports insoles [Footcraft] have supported many athletes, and have focused on the soles of the feet as a form of sports gear that can be useful to even more athletes. In order to jump high and move forward powerfully, the contact point that grips the ground and transmits force is important. However, a collapse of the footbed can cause various worries and problems. [Selectable Arch Types for Optimal Support] Everyone's foot arch shape and concerns vary, from low arches to no arches or high arches. Footcraft offers three arch types (low, middle, and high) to suit your foot. By selecting the arch type that's right for you, you'll experience a custom-made fit and achieve ideal foot balance. [Alignment based on the windlass mechanism] When the toes lift, the arch (plantar fascia) of the foot rolls up due to the "windlass mechanism." This is said to be the strongest state of the foot. Footcraft is designed to support the foot when the arch is at its strongest, allowing for accurate transfer of force to the ground and improving performance. Supporting the heel bone also enhances the natural shock absorption function of the arch, helping to prevent fatigue and injury. [High stability and flexible support] This patented structure* combines three layers of different hardness and surface area to achieve both high stability and flexible support. The first layer, a hard material called the "Core Stabilizer," provides the high stability required of a functional insole, while the second layer, a soft material called the "Flexible Holder," provides flexible support that follows the movement of the arch of the foot. *Patent No. 6982292 [How to Choose Your Arch Type] Footcraft insoles are classified into three arch types using our unique assessment criteria. Please measure your arch type using our arch measurement method and choose the type that best suits you. You can easily measure at home. Please see the images and video for details.
