The CIRCUIT combines incredible comfort with the demands of modern climbing. The newly developed last offers optimal toe space, and the slightly suggested downturn perfectly supports your foot. Designed for beginners and comfort enthusiasts, the CIRCUIT still offers sufficient performance for advanced sport climbing and bouldering, multi-pitch tours, and long training sessions. The RC-SUPPORT midsole provides sufficient support, and the extra padding at the ankle adds extra comfort. The new, innovative TPU mesh, which forms the middle part of the shoe, is very soft, breathable, and extremely robust. The CIRCUIT fits your street shoe size. For the best fit, we recommend measuring your feet using our size chart. UK sizes 3-12. Two opposing hook-and-loop fasteners for optimal adjustment. A very comfortable climbing and bouldering shoe for long sessions, multi-pitch tours, and long training sessions.
