"The exclusive Karakal non-marking outsole with its built in turning circle is designed to make direction changes easier. The extra tacky Gum Rubber compound gives great adhesion when the foot is planted, deep grooves across the forefoot allow the toes to bend naturally and the TPU Anti ? reverse bend insert provides stability and has the potential to reduce foot and lower limb injuries. The Phylon midsole density has been adjusted for maximum comfort and support, the under-heel shock absorber and EVA layer under the High-Density Performance Insole add to the shock absorption properties. The upper uses the highest quality Microfibre materials for the support areas and the mesh allows the foot to breathe.
