I really like the shoe and it does relieve a lot of my foot pain. The only thing I would change is to add the extra rivets for a heel lock. I’m having problems getting the shoe laced tight enough where there isn’t slipping on my heels.How would you rate the arch support of this shoe?Rated 5.0 on a scale of 1 to 5How would you rate the style of this shoe?Rated 3.0 on a scale of 1 to 5How would you rate the comfort of this shoe?Rated 4.0 on a scale of 1 to 5How would you rate the size of your shoes?Rated 4.0 on a scale of 1 to 5How would you rate the width of the shoe?Rated 1.0 on a scale of minus 2 to 2How does the size of your shoe fit?Rated 0.0 on a scale of minus 2 to 2KFKURU Footwear2 days ago

- MMMichelle M.Verified BuyerReviewingQUANTUMI recommend this productRated 5 stars1 week agoSo Far So Great
This is my first day in my Quantums, so I’m still in the breaking period, but I’m loving them! I’m not sure yet about the arch support, as that is what I’m after, but that takes some time, I understand. However, the toe room is amazing! My toes do not feel squeezed at all, and even have room to spread. This alone is worth five stars!!How would you rate the arch support of this shoe?Rated 5.0 on a scale of 1 to 5How would you rate the style of this shoe?Rated 5.0 on a scale of 1 to 5How would you rate the comfort of this shoe?Rated 5.0 on a scale of 1 to 5How would you rate the size of your shoes?Rated 3.0 on a scale of 1 to 5How would you rate the width of the shoe?Rated 0.0 on a scale of minus 2 to 2How does the size of your shoe fit?Rated 0.0 on a scale of minus 2 to 2

Understanding “FIT” notes:
ALL KURU shoes are sold in US sizing. IF the “FIT” note says “1/2 size small”, you should purchase a 1/2 size larger than your normal size (e.g if wear an 8, purchase an 8.5). If the note says “1/2 size big," then purchase a 1/2 size smaller than your normal size.
