The daily shoe.
Size: 13, Color: Black/Anthracite
Great daily running shoe! It took approximately 3 weeks to fully break in, but now they feel incredibly comfortable. My feet stay nice and cool throughout the day. I went on a light waterfall hike and the water resistance held up fine. The shoes look great; in direct sunlight they look a little dark blue, but they are still perfect for work.

Nice fit, classy looking sweater
Size: Medium, Color: Navy Blue
I bought this for my husband because now that he is retired and lost weight, he needs casual clothing to go out and socialize.
This sweater is both classic and sporty, working well in a golf course or a night out. It is soft, washes well and fit perfectly. I am ordering more in different styles and colors. It is light weight and not bulky.

Nice sweater
I wasn't sure what to think of this sweater. It looked nice, but I don't know. Then I wore it out one night. I totally got laid that night. Highly recommend.
