Plus, you get a comfortable and snug fit around the heel and midfoot. Personalised Heel Fit consists of two layers of memory foam lining the collar that moulds to the heel, creating a personalised fit. Vented Magic midsole and outsole minimizes weight and maximizes breathability. Rearfoot GEL provides cushioning in all directions absorbing impact forces and helping to stabilise the foot during heel contact. Forefoot GEL reduces the loading forces as the foot moves into propulsion, improving performance and minimising the risk of injury. California Slip Lasting for stability and comfort. Upper is stitched around a canvas or EVA board and directly attached to the midsole. The Solyte midsole is a proprietary cushioning material that provides an exceptionally lightweight midsole with excellent bounce-back and durability. The cushioned sockliner can also be removed to accommodate a medical orthotic, meaning this shoe can cater for, and enhance the performance of young runners regardless of age, style and ability.
