I was poking around on Wal-Mart's website trying to find a tall boot for my Han Solo Costume when I stumbled upon these rubber boots:
Walmart.com: Tingley Men's Half Boot: Shoes I had some success sealing then painting rubber boots last year on my Boba Fett suit. I used a poly-acrylic water based sealer and painted it on the boot. Once it had dried, I was able to use regular old rattlecans to mask off and paint the boot however I wanted. Super-glued thin black shoestrings to the front for the "ribbed" part and it held up well.
These Wal-Mart boots are $43 bucks, so they aren't the cheapest, but if you wanted to save a bit and were feeling crafty, they might do the trick. Just wanted to pass it along. And you just have to have the closest boot I've ever seen to the screen used boot, save that 43 bucks and put it towards a pair of Man of War's boots.! They are the bees knees! (saving for a pair of his myself)
