Perfect fit with no socks, that was the goal. Use them for boat trips and evening wear with linen trousers. Husband says they're a little uncomfortable but will probably be fine once they're put on. This is normal for the skin. Would have preferred a slightly different style but couldn't find the ones he wanted in his size. It was the second option because they were his size. Others were cheaper but these are good for the price. More like slippers than shoes but good enough for the purpose they were bought for.
