I love my Crocs and lived in the Croc sandals all summer and fall.  I purchased these because I wanted a heavy duty Croc that would have better tread on slick surfaces, and one without so many air holes in it to keep my feet warmer for winter.  Well, it does fulfill those requirements.  I like the way it looks, but unfortunately that's about it.

The top edge across the instep has a rigid finish that is uncomfortable, and to wear these for more than a few minutes isn't working for me.  IT seems to cut into my instep.  Another issue I have is in the sizing. I bought the same size I've worn in regular Crocs and in Croc sandals, but it seems to be smaller so my toes hit the front.  The size issue I can work around by not using the strap, but the top ridge hurting remains an issue that may be resolved by short wearing sessions or not.  Only time will tell.
