I ordered this sock with the special cuff but all I got was the regular waterproof sock from Big Edge, which I already have.  I can always use another pair of the regular waterproof sock, but it certainly doesn't give you the water seal promised by the product that I had ordered. I noticed that Big Edge was gracious enough to mis-label their the packaging, going right over the original label, although the top of the package clearly says "all season socks". The cuff seal is not there, so if you ordered the sock with a cuff seal and then were sent the wrong thing, you might have a water leakage problem. Since both the regular all seasonwaterproof sock and the SealSkinz with the In Cuff Seal in fact have a cuff, you could be misled into thinking that you have the one with the waterproof cuff. So, buyer beware. I'll keep the socks, as I said I can always use them, but it was disappointing to get the wrong one. Do NOT use Big Edge. The three stars I am giving is really a combination of 1 star for Big Edge and 5 stars for the regular sock (sans In Cuff Seal).
