The various footholds offer your feet plenty of options. A targeted use on your climbing wall complements the overall picture of climbing holds. The Foot's can be found in the Biometrics series. It is the successor to the Polygon series and impresses with bionic patterns on geometric building blocks. The holds are made from polyurethane resin (PU), which is additionally processed with a special mineral filler. Unlike pure PU holds, this combination significantly increases abrasion resistance. The stability and break resistance of the holds are also very good despite the mineral filler. The climbing holds in colors white, blue, purple, dark green, and neon are not UV-resistant. This means that outdoor use may lead to discoloration of the climbing holds. However, this does not affect the stability of the climbing holds. Screws and nuts are not included in the delivery. Please order them separately.
