The little booger ordered these online and didn't tell me until a couple of days ago. The UPS man just left and he couldn't wait to finish eating his lunch to check them out! These babies have extra "floaters" to add to the backs of them when walking with your backpack on to support the extra weight, and they even move in the middle to dig into the snow when walking up steep embankments. They're awesome! Now all he needs is some snow for his brand new snowshoes.
