The Ridge High GTX is described by Mammut as a boot for via ferrata and backpacking. At 1476g (pair, size 11) it is certainly light, which is useful on via ferrata routes and when scrambling. The upper is softer than many boots in its price range and the foot also feels closer to the ground, which overall gives this a feeling of a multi-activity shoe rather than hillwalking boot. But there is more support in the heel cup than a shoe and also the toe box gets a rubber rand for more protection. The ankle cuff is quite stiff too, which feels a little uncomfortable compared to some other more conventional boots. The outsole is quite flexible, again making this feel a little like a multi-activity shoe. The lugs are quite deep and widely spaced, though, and the grip on soft ground is good. There is also enough stiffness in the sole to prevent stones pressing through the sole unit. For me the Mammut Ridge High GTX is a rather odd boot. I can see it being useful for valley, moor and hillwalking and even for trekking, but for mountain scrambles I’d prefer something a little stiffer throughout. The bid advantage is the weight of course, so you need to be keen on that weight saving to compensate for the performance difference compared with other more mountain-orientated boots.
Upper materials suede leather, synthetic textile
Waterproof lining Gore-Tex

The Mammut Ridge High GTX is a very lightweight boot but the ankle cuff, upper and sole combination is an unusual mix that delivers a unique performance that you might have a love-hate relationship with.
