Best ultra trail running shoes for 2025: Go further, faster

Scarpa has a range of trail running shoes for all eventualities, but what the Spin Infinity focuses on is providing that necessary structure, comfort and stability for the longer distances. 

The neutral, midweight trail shoe has a good level of structural support. The foot-wrapping overlay reaches up to the laces, which can be tightened to create a snug fit that hugs the foot in place, while a rigid heel counter offers more structural support. This is combined with a 4mm drop and slightly curved dual-density foam midsole, all of which come together to create a shoe with a good overall level of structure, without falling into the trap of becoming too stiff and unwieldy.

There’s a decent amount of padding along the heel and in the tongue, which Scarpa calls their ‘Adaptive Cushioning System’, it helps to keep the foot locked nicely in place, avoiding any heel slippage. The stack is also in that mid-range at 26mm, which offers ground protection without making you feel like you’re running in high heels.  

Thanks to the panels of open mesh along the upper, the shoe manages to remain quite breathable in motion. There’s protection there too with the gusseted tongue and extended TPU toe bumper to protect from trail debris. A mesh pouch at the top of the tongue is there to tuck in laces, in theory this should prevent them coming undone mid-run. 

Vibram Velox Cross lugs are 4mm in length, which means they can tackle a range of terrain but fare best along dry and less technical trails. Overall, the Scarpa Spin Infinity is a great all-rounder trail shoe that can hold up over those longer runs where you need that bit more support and comfort.
