Ridiculously narrow compared to another pair of FitFlop sandals I have.  I don't know if the soles differ by style or if they have changed over the years (my older sandals are about 2 years old), but the soles on my other FitFlops are 0.5&#34; wider than these.  I wear an 8.5 and bought a 9.  My feet cover the entire width of the soles of these shoes, but my toe tips are about 2 inches from the front of them, so my feet look like spatulas standing on skis.  Luckily, I bought them to wear around the house, because they look really stupid due to the fit.  Granted, I have short wide feet, but the great fit of my old pair is what drove me to buy these.  For reference, this is my old pair: http://www.amazon.com/dp/B005LBYOSW/ref=twister_B008DTGDBU
