These shoes are so light and airy, but I ended up returning because I only need a half size bigger and this brand does not offer the 40.5 as some other brands do.  I was concerned that the 41 would be too large (I typically were a women's 8 1/2 or 9 in US sizes).  I went to a local bike shop where I tried on shoes, got the best fit and didn't have to pay shipping fees (the seller did not charge S&H but now that I am returning them I will be charged the original S&H and will be deducted from the return) .  They are really cool looking, perfect without socks, and so quick to get on and off.  I don't ride competitively so maybe they were the right shoe for me to begin with.
