Do they stretch??
5’s are a bit too small in length but fit better in width - and look better as the laces go wider. This is with thin normal socks, I think thicker wintery socks might make them more tight all round as my toes do feel a bit squished.
6’s are too big. A good thumb between toe and end, feel like they are flapping around a bit. And the laces look v pulled in tight which IMVHO makes them look a bit dweeby (for want of a better word).
I love them though.
So…
5’s and hope they stretch or 6s with an inner sole??
