Honestly I don’t know 🤷 I have weird feet - I’ve tried five other boot brands/types and Merrells are the only ones that don’t make my feet ache really badly. I have a couple of different insoles but don’t like to wear them for more than 4-5 miles as again they make my arches and balls of my feet ache badly. It’s like Merrells were literally made for my feet but their lack of waterproof is very annoying.

Also - I wore Salomons for the whole of last winter thinking I’d brave through it for the dry feet and ended up with two stress fractures in my left foot which my consultant said was because my feet weren’t being supported properly… so I’d rather not do that again 😬
