They look like a narrow fit. Would you agree?
I would say "an Italian fit". I usually take size 8 (42) but in these and Sidi I take a 43. These are my summer touring shoes for use with thin socks, by comparison my Exustar Stelvio in 43 are for use with very thick socks.
Taking advice of reviews, went a size larger (45) which were perfect. They are a narrower fit than my Stelvios which are really too wide for me with ordinary socks - will try them with thick ones! Getting spare treads is a good idea as the shoes otherwise look like they will last a long time.
