Through the reviews there was a trend that the boots ran 1/2 size too small, so I sent the shipper and email to change my size to 1/2 size larger and they did.  The boots fit perfectly.  What I didn't like was that the insert has already started to come out in 3 day use. It is a little annoying after taking them off and having to stick it back inside. Any way, great customer service, a great pair of boots except for a minor problem.
