Damfino who made mine. But two caveats:
Metal zippers can freeze up really good over the winter, look for YKK plastic. Don't ask me how I know this or why I was diving with duct tape on my ankle.(G)
And the removeable inserts ARE very nice. Small nuisance, you have to remove them and replace them when you rinse and dry the booties, or else they trap water, stay damp forever, and breed mildew in there.
You can also apply "Shoe Goop" on the soles for traction, and to prevent wear. The stuff is similar to AquaSeal, but way cheaper, and very durable.
