Bought a pair for my deployment in Nov 12. It's mid Jan 13 and the soles are separating along with the inside liner is failing.
The inside liner is too thin and while it performs well for keeping my feet dry, it tore around the heal already. The soles are glued on which is normal for this style of boot but they are separating at the mid foot.

Magnum is standing behind the product 100% and is replacing them with out hassle and honoring their warranty.  I hope I just received a bad pair because these are the lightest and most comfortable pair of boots I've owned. The required zero break in and my feet are not sore from pounding sand all day. Great boot for feel, comfort and super light weight...they just did not stay together.
