While I haven't worn them many times yet, so far, this is a really nice pair of boat shoes. The leather is comfy and soft, and they give off a nice, rustic, casual look. The soles are nice and grippy.
They are a pretty unstructured moccasin-style shoe, so they aren't supportive, and I don't recommend them if you'll be on your feet and walking a lot.
In terms of sizing - here are some shoes I successfully wear:
- New Balance 880 running shoes in 10.5 D
- Allen Edmonds in 10D in their 65 last
- Cole Haans in 10
- ECCOs in (EU) 42
- Carmina in (UK) 9 in their Rain last
Based on comments, I sized up a bit and got these shoes in a size 11. This size felt great out of the box.
