I have been wearing them for about a month. I have never worn more comfortable, soft, and lightweight shoes in my life, to the point where I feel like I'm wearing nothing. They are really lightweight, ideal for walking. It is also very positive that the fabric is very cool, resulting in cool feet. They are definitely worth the money.
Update: I have been wearing them for the third summer and the insole lining in the heel area has barely worn out. No external damage. Very durable!!
