I have the exact boots you are talking about, they were great for the first little while...however after about 3-4 months the interchangable soles started to just interchange too easy , like when I'd kick my iced up boot on the pavement it would fall out, eventually after time rocks got in there and made the part that holds the sole too big and theyd always fall out. I ended up just using the damn things without the soles and the boots held up for quite a while longer, but due to the fact that the soles were a major pain from the get go I'd reccomend to stay away from them. Just my opinion though...
