Comfortable Shoes

This is the second time I purchased this style of shoes. They are extremely comfortable.
They can be worn on casual and business events.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

Mens shirt
Size: 17"-17.5" Neck 36"-37" Sleeve, Color: Lavender Blue Check
It's a very well made shirt. I got it for my husband, he has to wear this kinda stuff for work. He actually loves this brand of shirt. Very comfortable. I actually got it on Amazon days or whatever it's called. So the price was cheaper than normal:)

My original dress shirt in white.

Tried and true dress shirt but I love how the collar stays are actually sewn into the collar.
