These are awesome, and awesomely big.  When I slid my foot in the first time I was amazed at how hugged they were by the liner and how soft they were all around.  Super warm, very comfy, waterproof, and tough and not bad looking either.  I think I'll have these for the rest of my life and I'm 30ish.  These replaced a pair of laced Sorel's that I had for 10+ years that were starting to fade and I couldn't be happier.

A couple caveats that don't really bother me but are good to be aware of:

I need to wear high socks with these otherwise a short sock will fall under my foot after some walking AND the top edge rubs uncomfortably against my legs.  They are huge and won't travel easily.

I probably wouldn't wear these for long treks but maybe they just need to be broken in but does rubber really break in?
