Figuring out sizing can be tricky online, but Wildling goes above and beyond to try and simplify the process. My first pair ended up being just a little too large, thankfully they have an easy return process for your first order. I'm based in the US so working with DHL for return shipping isn't the greatest (they're more streamlined in other countries) but overall not bad. My replacement pair is the perfect size and I've never loved putting on a pair of shoes so much in my life. I'll be ordering another pair when the weather warms up and take these with me everywhere I go.
