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.

great waterproof cell phone case.
needed a waterproof case for my cell phone when working Emergency Communications with my Amateur Radio equipment and it's raining or snowing. This should work well to protect my cell phone. Zipper seems are sealed really well. Tested the case using sink prior to using with a cell phone.

Well made and air tight
Love the little pouch it comes in handy for camping,hunting and fishing if your in not so great weather. Not sure how the zipper is made but it's definitely air tight and can feel the difference when sealed. The zipper is a little tough opening and closing but that's probably due to the nature of it being waterproof. Hope it stays that way after long term use!
