I just ordered a pair of the Abyss boots.  My main concern is ankle support.  I have always used hiking boots mostly for the ankle support.  I had always shied away from the Quetico Trekkers as they didn't seem to provide as much support.  I am hoping the Abyss is better than the Quetico Trekkers in that area.  

I hate that they don't have 1/2 sizes, as I am right in the middle.  I ended up getting the size up 12's as I would rather deal with something a little big than too small.  

Thanks for the reviews and if anyone could offer something on the ankle support and sizing I would appreciate it.
