Seemed like a great deal, so I bought several pairs for the groomsmen in my wedding.  Every pair went back because they were all about 1.5 sizes too big.  I wear a 9.5 and the 8.5 that I purchased was still too big for me.  Also, I don't think the material was very high quality - but that is only from the flimsy feel.  Never worn longer than to try them on and send them back.
