Winter Snow Boots for Women Suede Cotton Warm Fur Lined Ankle Boots Outdoor Anti-Slip Waterproof Booties Lace Up Platform Shoes Grey

How cold of temperatures are these rated for?

How is the traction on these boots on icy or slippery surfaces? They list that they are anti-slip but need something that will be grippy on ice.

I wear a 9/9.5. should i follow the size chart (size 12?!?) or my normal us size?

My ankles are 11". Would a size 10 in women fit me?
