I read the reviews and decided to give it a try. These shoes were initially quite comfortable when I placed them in my living room. However, that changed when I took them running/walking. The first thing I noticed was the lack of lateral support. I tightened the laces, but that didn't change anything. In addition, the shoes rise very high at the heel. It is not a very flexible material and the material is very rough and will blister within 15 minutes of running/walking. I tried them again (after buying taller socks) but the heels dug into my ankle again and the flimsy construction and lack of support was quite uncomfortable. I won't be using it anymore and I don't recommend it.
