Who should NOT buy it

The featured Mammut boot is gated behind a high paywall. In its place, check out the Danner Vital Trail, which is part of our budget-friendly lineup. Also, you might be better off purchasing the Salomon Quest 4 GTX if you want a pair with a more glove-like fit.

Says no to wobbly arches

"It feels strong and supportive" is how a critic finds the boot's arch zone. This is thanks to Mammut's Flextron Technology, whose presence gives the trail-goers a nice blend of stiffness and torsion control underfoot.

Not weighty at all

Adventurers adore the Sapuen High GTX's lightness, with a gear pundit among them describing the featured boot as "incredibly light despite its sturdy construction." It's "like a slipper for me," says a non-professional reviewer among them. Also, FYI: the shoe in question weighs 530 g per kick, while the average weight of high-cut day hiking boots is 580 g.

The Mammut Sapuen High GTX's royal price tag

You wouldn't be aiming too far off the mark if you said that the "High" part in the waterproof Sapuen's name also relates to its demanding asking price. But in all seriousness, at $189 a pair, the featured hiker is not for the faint of heart. After all, it's $47 more expensive than the average cost of day hiking boots, which is $142.

Mighty grippy

"Great" and "very good" are the words wearers associate the Sapuen High GTX with on the surface traction front. They praise the boot's outsole for providing exceptional stickiness on various surfaces (i.e., loose stones, and muddy tracks). "They’ve held up great so far in snow," says another.

Fantastic fit around the ankle and heel

"It fits really well right up the ankle," says a professional reviewer. Experienced trail-goers pretty much say the same thing, too, but with one applauding the heel, in particular—stating that it has no lift at all.
