I bought these shoes for home workouts, both lifting and aerobics. They're very stable, have the perfect amount of cushion without compromising stability, and are comfortable. They run a bit small; I'm usually a 10, ordered a 10.5 and my toe is at the end. They're snug but not tight and seem to have a good amount of room in the toe box. I'd recommend these.

My walking shoes

Size: 8.5, Color: (418) Blue Smoke/White/Nu Blue

I bought these last year before a vacation when I knew we'd be doing miles of walking a day. I had ZERO blisters breaking them in and immediately walking 10k+ steps in them. Now they still get a lot of wear at home for outings when walking will be involved. No issues, very comfortable, would recommend!

Don’t pass these up!

Size: 9, Color: (673) Tourmaline Pink/Summit White/Maroon Mist

I’m 67 years old, 5’3” tall, and weigh 117 pounds. I bought these shoes to wear during my daily “walking workouts “. When I first tried the shoes on they seemed too firm but I decided to give them a try and I’m glad I did! The cushioning was excellent and there was ample toe room. The color of the shoes is the same as the picture - and is really pretty.

Love them!

Size: 10, Color: Enamel Blue/White/Illusion Green

I love these shoes! Lightweight. Got a 10. True to size. My feet are a bit wide, and these are comfortable. I ordered another pair! Compared to shoe store prices, this was a deal.
