I usually wear a size around 12, chose 11.5 as suggested in Revain's small digital guide when I filled it in but I found that they felt a bit felt tight. Maybe they just need a little break, but time will tell. Otherwise, they're comfortable, just like the previous couple (who were 12 but felt like losers). My previous pair had serious traction issues in slippery conditions (like rain) and lived in the Seattle area, well it rains there, but they were also about 2 years old so maybe it was just time. It's a good balance for casual or day-to-day work, which is what I was looking for.
