Nice concept but after only 2 months of ownership I completely rubbed out the sole. I haven't walked too much or been rough in these shoes, the upper looks perfect. But the tread was completely worn out within a few weeks and the material underneath the sole is now exposed on both shoes. PROS: - washable - available in different widths - upper looks nice and stretches a bit CONS: - tread material is so soft it wears out very quickly. I guess they won't keep me for more than a few weeks. Owned for less than 3 months.
