The fit is identical, but the VOLTAGE LACE model is a little 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.
