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.

Nice Short Sleeve Casual Shirt
This is a very nice casual short sleeved shirt. It's not too thin or thick. Being button down, you could even wear it with a casual jacket for semi-formal events. Look closely at the pictures, this isn't really a solid color, it is a woven pattern that gives the fabric a textured look. 5 stars for being a nice shirt that is as advertised. It washes well and is comfortable.
