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.

Durable
Style: Bi-fold
My man loves it. He works construction and it has held up well so far. Carhartt does good work. Looks exactly like the picture, well made.
