Just so happens DH had to buy a new pair last week.
He shopped around town. There were a very select few on sale. Sports Authority had some at a good price, but only one size (and the wrong one).
At another sports store, the sales person said he use to work for Teva. He said they only produce them a few months out of the whole year.
To get what he wanted and in his size, DH bought them from the Teva web site. They weren't an exceptional price, but a little lower than usual.
