"Great boot. I see what other buyers are saying- but luckily i read their reveiws first before ordering. I have relatively slender feet but went with the W. The boot goes on just fine. I wear an 8.5 and got 8.5 W. Good feel. it's a bit stiff but it's a robust boot and prob just needs to be broken in a bit. I love the way it looks. also love that it's water/mud proof. Can't wait to test that out. I also scotch guarded it Just in case. :)"
