The Matman #SO40 G5 Revenge Wrestling Shoes are made of a leather and breathable mesh upper combo to help aide in whisking away excess moisture and humidity from the foot. It contains a new tongue channel that was specifically designed to hide and keep the laces in place. Its new split sole design improves the flexibility and durability of this wrestling shoe. It features a gum rubber outsole to enhance performance and traction on the wrestling mat. The #SO40 also features a wider fit than most wrestling shoes.
