As recommended by other water shoe purchasers, I did buy a 1/2 size bigger and glad I did. The laces hold well and the fit is great. The shoes dry nicely. I haven't had any problems with cracking (as other shoes have done) and the durability is excellent. I use them often for running laps in the pool and the support is great on my foot. I do recommend these shoes and would buy them again if needed.
