When you look for professional motorboots, then Dainese is the right brand. The torque d1 out Gore-tex is one of the few racing boots with a fully waterproof membrane. With functions like the TPU rear inner insert (D-Axial System), shock absorption insert on the heel with controllerd deformation insert, a nylon heel, reinforced nylon toe and protective nylon inner hull, it is not that strange that these boots are certified to CE - Cat. II - EN 13634 standard.
