With the fit of the VOLTAGE, the model VOLTAGE LACE is slightly stiffer and thus offers more support at the forefoot. This makes it particularly suitable for difficult routes on steep and overhanging crags. The wide, anatomically designed last with a powerful downturn remains. This optimally supports the foot when standing on small footholds. Additionally, the leather parts in the footbed adjust themselves to the toe shape. A thin lining in the toe box increases comfort and prevents the stretching of the upper material. The asymmetrical lacing makes individual adjustment possible and allows a better pressure distribution on the instep. In addition, this arrangement provides more space for the large toe patch, which remains flexible thanks to well thought-out cuts. The lacing system can be tightened evenly with a single pull and is reinforced at neuralgic points. The overlapping tongue, which covers the instep, avoids unpleasant pressure points.
