Does any one know what the old reebok's with the zipper in the middle are called?

They are similar to Allen Iverson's shoes, but the material that surrounds the shoe is of a stretchy, soft material, sort off like what womens bikinis are made of. They have the big reebok logo on the side of the shoe. I used to own a pair when I was younger, they came out like 5 may 6yrs ago. I tried searching all over, but wasn't able to find them, if any one has a clue, or can point me in the right direction, I would appreciate it.
