Solid sneakers—worth it on a good discount
Size: 9, Color: Vintage Indigo Canvas/Natural
These sneakers are solid overall. They look good and feel comfortable for everyday use, and the quality is what I’d expect from the brand.
One thing to note: if you have to walk a lot, they can start to feel less comfortable on the top of the foot (upper area). It’s not a dealbreaker, but you’ll notice it on longer days.
That said, they’re definitely worth it if you catch a really good discount.

Comfy but ouch!
Size: 11, Color: Stormcloud Canvas/Sleet, Size: 11, Color: Stormcloud Canvas/Sleet
Nice style that keeps its shape, comfy insoles, true to size. I got the grey color at size 11. However the back part of the shoe ripped into my skin. I had to wear band aides after the first day of walking during our vacation. So wear sock that cover the back ankle. Otherwise, I like these shoes.
