AKU Spider Light GTX 2012

The AKU Spider Light GTX features a unique upper design called AKU Air Infinity Technology, using materials more breathable and lighter than leather. To further enhance breathability, a thermoplastic PU frame provides support to the upper while leaving large areas of fabric open to the air. There is a Gore-Tex waterproof lining too, to keep your feet dry, plus a rubber rand at the toe and heel for extra durability. On the foot these boots feel great and benefit from a more rounded toe than some, which makes them comfortable for walking, although perhaps not quite as good for climbing because you cannot get such precise toe placement. Underfoot there is a Vibram Mulaz sole, which is more of a climbing-orientated design with a smooth ‘climbing zone’ under the toe. The combination of a lighter design and more breathability makes this very appealing, while the broad performance range is very good; but some boots have a more aggressive outsole and a full rubber rand for durability, which may be an advantage to walkers, while other boots here offer a more precise climbing performance. There is no women’s version of the AKU Spider Light GTX.

The AKU Spider Light GTX offers an unusual mix of features with the main benefit being the reduced weight and increased breathability, but performance is less specific than others.
