Mammut Merlon GTX (2013)

The Mammut Merlon GTX appeared in Spring 2013 and it is very competitively priced for its specification, as well as a good weight of just 1746g (size 11 pair). It has a Gore-Tex waterproof lining behind the upper, made from layers of leather and synthetic materials with a rubber rand to provide extra durability. The ankle cuff is a notch lower than some boots and also a little more flexible, so this boot feels great for walking – but when mountaineering you might prefer more ankle support. Underfoot there’s a very good sole with reasonably deep lugs that are well-spaced to prevent clogging. You also get a smooth climbing zone under the toe. The toe is slightly more pointy than some boots and this, combined with the close fit, makes it ideal for scrambling, via ferrata and climbing. The only drawback is that the Mammut Merlon GTX isn’t as stiff in the sole or as supportive in the ankle as some higher priced options, so for longer days on snow-covered slopes, other boots have advantages. A great option for those that don’t need the ultimate performance in snow but do want low weight and good performance on rock.

The Mammut Merlon GTX is a relatively lightweight boot that’s very well-priced and ideal for scrambling, via ferrata and easy snow slopes.  It won Trail’s ‘Best Value’ award.
