Classic II Adjustable Calf Waterproof Rain Boot (Women)

This is my first pair of Bogs boots, and the adjustable calf on these is what drew me to them. What a difference it makes; it is actually the best part of this boot. No longer stuffing pant legs inside or having them ride up your leg either. They have kept my feet pretty warm in the cold temps and snow we've had recently. I feel they run small though. I wear an 8.5 in average width, and I've always sized up to a 9 in other brands which have given me a little extra room for thicker socks. But with these, thick socks make them way too tight. Not sure if a 10 would be too roomy or not. I'm curious to see how long they last, and hope they don't crack after 2 winters like other brands I've worn. Have had these less than 2 months, so hopefully they'll last longer than 2 winters.
