The BTII shoes feature a Boa Fit IP-1 closure system. Made of perforated microfiber, they facilitate perspiration, especially in the instep area. The TPU heel is semi-rigid, includes a rubber reinforcement on the toe, inside and outside, which improves its resistance.
The sole is dual density and is manufactured with the Hebo Optimum Pedal Sole System (H.O.P.S.S.), patented by the brand. The durable polyurethane midsole combines well with the automatic internal insole. The ankle is reinforced to correctly fix the position of the foot.
