Ideal boot for the winter, snow, mud, etc. Protect your feet beautifully, stylishly. Tip: Wear with two socks to help break in for the first couple weeks. If you are a half size, round up. This is the model without laces, makes for easy slip on / slip off for those pesky people who insist on having you take off your shoes at their house! Ha ha, you know who you are.

Size up for a little bit of heel slip

Size: 9 Women/8 Men, Color: Black Nappa

It’s still a doc and the air sole with bottom out kinda quick but it’s comfortable at first. Size up for a little bit of heel slip so you don’t get heel blisters but not too big of a size jump. Think of it kind of like a cowboy boot size

Comfy, don't require "breaking in"

Size: 8 Women/7 Men, Color: Dark Brown Valor Wp

Great fit, and both my pairs of Chelsea boots required way less breaking in than other Dr. Martens I own. Hold up to frequent use and I love the fleece lining for colder days.
