I bought the Merrel Prevoz in black, and have been wearing them all week.
In Switzerland they laughed at -10' and snow, even though I only had tights on underneath. Today, they were lovely and grippy on the ice on our pavements.
I have wide feet and chunky calves, but the lacing adjusts perfectly for that, but they zip up, so no adjusting each time
