Reactivearch technology: Reactivearch is the dynamic sole with a concave form. It flexes, moving in unison with the natural deformation movement of the transversal arch in the forefoot. It favours the subsequent elastic return of the forefoot, what we call 'energy return'.Stitched Outsole: The outsoles are stitched to the upper to increase the longevity of the footwear. Puntoflex: Puntoflex is a special technical device which allows the foot to flex correctly and gives an excellent elastic return.Features Include:Outsole with dual-geometry studs for maximum traction.PU and bovine leather upperSuitable for firm ground surfacesControl boots
