AKU Spider Light GTX 2009

As the name suggests the 4-season AKU Spider Light GTX is a lightweight boot, yet there is also plenty of winter-orientated performance here too. The upper is made from synthetic Air8000, which is more breathable than some other synthetic materials, which means you should not get as sweaty in this as in other boots. There is a waterproof lining too, to keep the feet dry in wet snow. To protect the upper and provide extra support there is an external frame, while a rubber rand adds further protection at the toe and heel. The boot feels great on the foot and promotes a very natural walking action. The profile allows the wearer to experience a good feel with the rock, and this boot felt great for scrambling and climbing over mountaineering terrain. The sole unit has a climbing zone around the toe to further improve performance here. But the AKU Spider Light GT’s sole lug pattern is not the deepest, but equally it is not as shallow as some either, making it acceptable for winter use but not ideal. The boot does not have the extra insulation of some boots; and in the long run those boots with single-piece uppers or complete rubber rands may be more durable.

Verdict
