This is the unstudded version of Juniper BUGrip. Same design of upper but instead of a BUGrip outsole this version has an un-studded rubber sole made of RB9X compound. Among all rubber compounds we have encountered this is the one with the best grip on both wet and dry surfaces. Juniper RB9X is probably the most competent un-studded winter sneaker on the market. Material: Textile, Mesh, Rubber.
