I need to traipse through a lot of snow, so I wanted something with good traction, easy on and easy off. Since I love to schlepp around in Crocs during the summer,these looked ideal.  Yes, the soles on the Woolly Mammoth clogs are great and the back strap added just the extra security I needed for slippery walks--however I'm very disappointed that after wearing them for about a week, one of those garter-like clasps that holds the back strap to the clog became irretrievably lost in a mall, rendering the strap useless. I tried to improvise, but was unsuccessful. I ended up taking the other one off, too. Also, the linings didn't hold up in the back. One has become like a pesky sock that won't stay up. Well, these are my winter shoes and I'm going to be wearing them until the weather warms up. And in our little part of the country, the groundhog did not see its shadow, so I am hoping for an early spring.
