CimAlp 864 Drop Evo F: first impressions

When it comes to women’s trail running shoes, CimAlp 864 Drop Evo F offer something a bit different: they come with three pairs of insoles, allowing you to switch downwards from an 8mm to a 4mm drop. Also known as offset, different drops will suit different runners’ strides (whether you’re a front-foot, mid-foot or heelstrike runner) and surfaces – a lower drop is typically better for trail running, as it provides more stability and trail feel. 

This is brilliant if you are getting into trail running more seriously and want to work out what your natural stride suits, or if you’re experimenting with transitioning from road to trail running, or like to do a bit of both. 

Even if you know what kind of runner you are, switching to less drop on more technical terrain and then going back to more drop on groomed trails and tarmac might suit you nicely, or you may want to experiment with dropping down to strengthen your Achilles heel.

CimAlp 864 Drop Evo F: on the trails

It was good to be able to mix up the drop on these shoes, matching the off-set to suit the terrain we were running on. We found the 6mm insoles, handily labelled “Perfect Balance Drop”, just right for most trail runs on mixed terrain. 

We always rate Vibram soles when testing out trail running shoes and hiking boots, and CimAlp’s are no exception, offering reliable grip even on wet, uneven ground. 

We were also impressed with the fit of the Drop Evo straight out of the box – it’s as cushiony as a pair of casual trainers even when using the thinnest insoles, with plenty of room around the toes if you have wider feet (see also: how should trail running shoes fit?).

The Drop Evo is a good trail running shoe all round, so is it worth picking this design for its range of insoles? We think definitely yes if you fancy experimenting with drop – after all, they don’t cost more than other trail shoes, they perform well and they leave your options open if you change terrain.
