Anybody know anything about this boot? I found some for a decent price online, but have never heard of them. I know about the pronghorn gtx snakeboot, but never heard of the sharptail. Seems to be similar to the Pronghorn, except it's a slip on and not camoed. Also has two buckles on it, I assume to adjust the fit at the top and the ankle area. The add says it's 17" tall and has a gore tex liner. Anybody have any info, that has used this boot?
