Picked these Swims up yesterday at the Orvis outlet. Posting here to share some sizing info as swims are the very best galoshes available. I wear a Barrie 10 or 10.5 D. The Swims pictured are 2XL and fit over my 10.5 LWBs just right. Any shoe larger would be a struggle. I can also get these over my 10D SWB boots with commando soles and tankers on commando. I also have the Swims mobster boot in a 1XL and can't get them on a 10D with commando soles.
