Excellent comfort and quality
Size: 7 Wide, Color: (003) Black/Black/Bittersweet Pink
I loved these shoes. They are very comfortable, lightweight, and fit perfectly. I use them for walking and working out, and they haven’t caused any discomfort. The design is also nice and they look high quality. I would definitely buy them again

Size 11 is short.
Size: 11, Color: (110) Summit White/Summit White/Khaki Base
Am in process of returning them. The sole was very comfortable, but the size 11 was short. Arch support was good and appearance was fine. Disappointed that they are short.

I really like these shoes
Size: 9.5, Color: (023) Distant Gray/Bittersweet Pink/Boundless Blue
These shoes are cute with the different colors. The cushioning, for me, is great. I got them for a trip with a lot of walking and my feet, which normally hurt, didn’t ache at all. I feel they are true to size. The quality seems good. Despite all the walking I did, the shoes still look brand new. I am really pleased with this purchase.
