The Mammut Kento Pro High boot has a lot going for it – including comfort and a climbing zone that works well on steeper ground. This prompted Kirsty Pallas’ to give them her ‘Best Buy’ in 2023 winter tests.

The Mammut Kento Pro High is the only boot in this test that gives a warmth rating temperature, which is down to -20 degrees Celsuis. Between this and the 3D memo foam cushioning, it does seem to run small, and I could only wear a thin sock which still felt a bit tight, so I would definitely size up if I was getting another pair. It is well waterproofed, and the insulation is very beneficial especially when you’re standing around.

  • Rating: 4.5/5
  • RRP: £290
  • Weight: 1320g (EU38, pair)
  • Pros: Price, insulation

B rating: B2 | Waterproofing: Goretex | Upper: Velours leather | Crampon welts: Heel welt | Sole: Vibram Hexa Tech | Sizes: UK 3.5-8.5 with half sizes | Men’s version: Yes

The ankle collar is flexible with a dropped back which makes this comfortable for walking in. The tongue is connected to the boot with an elastic gaiter which reduces the profile in the boot. The top of the tongue is fairly bulky though, which makes it hard to lace into the ankle collar.

The laces start almost at the toes, which is good for adjusting down to the forefoot, but along the foot the laces run through fabric loops rather than metal eyelets. This does make it harder to adjust, and while it might mean the laces last longer, I’m not sure how durable they will be. Once you get to the base of the ankle, the hooks are metal, and there’s a narrow cleat to lock your heel into place while still allowing your ankle some flexibility. There’s also a really big pull loop on the back for helping get the boot on, useful when it’s a tight fit!

The sole is Vibram with prominent lugs, but not as deep as some. There’s a climbing zone at the toe, and with a neat fit, it works well on steeper ground. The rubber rand runs right around the boot, giving lots of protection to the upper.

A great boot with a lot going for it, but worth sizing up, and possibly more suited to narrow feet.

Testing conditions

Kirsty is a UK size 5/EU 38, with a wide forefoot. All boots (with the exception of the Aku) were tested during the winter of 2022/23 on both personal mountaineering days and while delivering winter skills courses, in all weather and conditions. The latter often involves lots of standing still and digging, so the waterproofing and insulation properties were well tested! The AKU boots are a new model so haven’t been tested in snow, but were used in cold autumnal weather on steep and wet terrain. Boots were weighed on Kirsty’s digital scales.
