Input: Odd shoe. Not comfortable for walking as it has very odd heel strike. Either the sole flexes too much or the heel is shaped oddly, I don't know. But, when walking in the shoe it loudly rolls on the heel and is uncomfortable. I don't recommend. I didn't notice this on carpet so much so after wearing to work on hard surface floors I don't want to wear them anymore. Really check them out before wearing outside so you can promptly return for a refund.
