My “go to” work shoes
Size: 9, Color: Brown
I think these look great, sporty and office appropriate for men as well outside of a really formal setting (wouldn’t pair with my suit but for chinos and a polo, it’s perfect!). The main thing I want to talk about though, is COMFORT. Man these are great! I’ve always had flat feet with discomfort after a few minutes of standing. With these on, I find myself using my standing desk for over an hour when I first get in and taking walks around the building during break time with ease. No tired feet when I get home and I think they look pretty cool to top it off. Great value.

Pleasantly surprised!
Size: 10, Color: Black
They look kinda of cheap and like old man shoes in the box. I was not expecting much as they were very inexpensive. They were boxed really cool with each shoe having its own sleeve and are true to size (Size 10). Comfortable and sturdier than they appear. They are very cushiony and look more stylish when you're wearing them. I thought they would wrinkle immediately upon wearing them but not so far. Was caught in a rainstorm and when they dried they were still like new. For the price (Just over $30 because I did not clip the coupon, grrrrrr!) they are well worth it. I am pleasantly surprised.

Fit Perfectly, Very Comfortable
Size: 11, Color: Black
I really love this shoe brand. I always play it safe with them — they’re comfortable, well-priced, and consistently reliable.
This particular pair stands out because it’s very lightweight, extremely comfortable, and fits me perfectly.
