The sole offers exceptional grip. The last is quite narrow.

Really good shoes that offer excellent grip above all else.
I bought them for orienteering, and—even as a beginner—I haven't experienced any slipping or sliding while running on slopes. They are also comfortable to run in on gravel roads, though they are truly in their element on trails.

Very good grip and was able to go for a longer distance without much break-in. The size corresponded to my normal shoe size.

Great shoes! The construction ensures that my toes don't poke through the front, even with rough use, making them a better fit for me than many competing products. Naturally, the upper material isn't as breathable, but feet sweat during activity anyway; I value the shoe's durability, lightness, and tread pattern more.

Light, best grip and do not mind water, mud or rocks, my second pair!

Fits the foot well like a perfect glove. The lacing design allows tightening/loosening at different points as needed. The grip is superior! The studs on the sole are a bit too high/takes a little getting used to. Worked perfectly even on a 3-hour trail run. Maybe the toe protection could extend a little further over the ball of the foot on the sides (this could of course make it harder to run). Overall, a very good shoe.
