I am after buying 'regular' Muck garden boots to this one Model changed two pairs before "normal" shoes. One problem with these earlier "regular" shoes was that they tore at an angle at the top of the shoe. after approx. 8-12 months of continuous use. Now I have these new "MUCKSTER II" shoes and they don't seem to have the same tearing problem. UPDATE: A year later, I still wear these "Muckster II Climbing Boots" EVERY DAY - gardening, pet care. . still intact. NO cracks in the corners (like 2 pairs of "normal" mud boots/garden boots). ONE THING THAT HELPS: I replaced the insoles with new/used sneaker insoles. cozy.
