The BRN insoles have an ergonomic design, tested by engineers and athletes, to improve comfort and performance, protecting the sole of the foot and reducing the possibility of running into sports injuries. To avoid the collapse of the foot and to counteract the dispersion of the power expressed on the pedals, the BRN insoles have been built with a patented longitudinal arch support. The cushion under the metatarsal raises and separates the small bones of the forefoot, thus reducing the pressure on the nerves and arteries, counteracting numbness and the onset of blisters. No more foot problems during long rides and high temperatures! To adapt to all types of arches, the BRN insoles have been designed with three different levels of support.
