V-Knit is a knitting technique that provides elasticity and adaptability to the feet. It is knitted in one piece to reduce layering and stitching. The sneaker is light and comfortable while the foot can breathe and stay well supported. This technique allows diminishing material waste because it doesn’t have to be cut at any moment, therefore, there is no waste.
The ThermoPlastic Polyurethane (T.P.U.) is a film glued on the sneaker. It provides additional seamless reinforcement, yet is very light.
