Outwardly Mammut Mt Centry GTX scrambling boots have a strong walking pedigree with a good rolling flex, plenty of comfortable padding and quick-lacing hooks; but lurking beneath their soft Labrador exterior is a hyperactive Border Collie just dying to scamper up some rocks. The tell-tale signs of this dual personality are fairly well-disguised, and come in the form of a well-designed tread pattern – which has a nicely balanced mix of climbing blocks and walking lugs – and a substantial rand. In action on the rocks, despite feeling a little numb, they stick well to both edge holds and friction holds, and provide a dependable platform. Jamming is a little bit fussier, as the metal upper lace hooks can catch on the sides of the crack or prove uncomfortable as you can feel them through the padding. The Gore-Tex inner and high cuff offer excellent protection against the wet, and combined with the impressive tread pattern these boots are ideal for damp UK conditions. One other plus, both for walking and scrambling, is the nicely refined heel support. This still allows enough flex for awkward moves on rock but also stabilises the heel well in potentially ankle-twisting situations.
