ORDERED 2 PAIR SIZE 8'S-ONE WAS SO LOOSE IT WOULD HAVE REQUIRED A SOCK TO NOT SLOSH AROUND. THE OTHER PAIR WAS SO SNUG WITHOUT A SOCK I HAVE TO RETURN THEM! MY BIG TOE WAS GETTING SMUSHED. I WEAR A WOMEN'S 9, AND SINCE MOST REVIEWS SAID THEY RUN SMALL, I GOT MEN'S 8 BUT NORMALLY WEAR MEN'S 7. EVEN @ THAT I STILL COULDN'T GET CONSISTENT SIZING IN THE SAME SHOE! NOW I WORRY THE NEXT PAIR WILL BE TOO BIG OR SMALL! IF YOU ARE A GAMBLER, GO FOR IT. THAT'S THE ONLY REASON I DIDN'T GIVE IT 5 STARS.
