I don't normally write reviews immediately after a purchase, but in this case it was justified. Shoes are narrow. My advice is to buy a few pairs. I usually wear a 9.5 US so I bought a pair in size 9.5 and one in size 10. Of course, the 9.5 was too small (I think it's thin), but the 10 fit perfectly. Also, shoes do stretch a little after wear, so take that into account. But they're good shoes and I think they'll last six months to a year, which is about as long as you'd expect a synthetic shoe to last . And at $80 I find the shoes a steal.
