Ecco shoes are very comfortable. Otherwise, I would have stopped wearing them years ago. HOWEVER, the soles are defective. I wore Ecco dress shoes for 20+ years. I was in court, on the road and with clients a lot. The neoprene soles are comfy but, at some point, the sole will begin disintegrating and falling off. At which point the shoes are worthless. Ecco replaced quote a few pairs, but the problem persisted. Sandals and tennis shoes? The adhesive binding the sole to the upper portion of the sandal/tennis shoe detaches, flops about and then falls off. Ecco has replaced LOTS of shoes for me. Finally, I got into the habit of keeping a couple pair of shoes in my trunk, since I expected a sole to fall apart during use....which inevitably occurred. I never travel with them. Nowadays, as they fall apart, I throw them away. My Ecco shoe inventory will all end up in the trash as they fall apart. Very sad since they're the most comfortable shoes I've ever owned. That, to me, was initially worth the aggravation.
