Good value
Size: 10.5, Color: Black/Black
They fit and they stay on my feet (I was worried because these are slip-ons).

Comfortable lightweight sneakers for casual everyday wear
Size: 9.5, Color: Navy
These sneakers feel like a decent value for the price. They are very lightweight, which makes them comfortable and easy to wear throughout the day, though that also means they feel a bit less substantial than more supportive athletic shoes.
I have mainly been using them with business casual office outfits, and they work perfectly well for that kind of light-duty everyday wear. I would not personally use them for anything especially active since they do not offer a ton of support, but for casual use they have been great. I also like how easy they are to slip on and off. I typically wear a size 9.5, and these fit true to size for me.
