I wear size 6.5 and followed the recommendation to size down to a 6. This usually works fine but in this instance they were too small. My foot fit in the clog but if I used the heel strap my toes hit the end. I was sad since the lime zest is adorable and they were $10 off. Size 7 would have been too big and also cost $10 more so I didn't take the chance. The size 6 in a $9.98 Walmart knockoff fit great so I think Crocs run small despite everything saying they run large. BTW the Amazon returns process through UPS is very convenient since I no longer have to waste ink printing labels.
