About 6 months ago I bought some OVS boots. I love the fit and function but they are built with cheap materials and they are cracking where they flex. I think the cracks are in some imitation leather. I see the RC modles cheap. With the Kangaroo leather do these hold up any better? A friend of mine has a pair and his have not cracked in over a year. I also don't like that mine are not very water tight. I guess without the cracking they would not be as bad.
