These were so comfortable from day 1, no break-in period, just comfortable. I usually wear slides but I wanted something that offered a shoe like feel because I kept getting small sticks into my feet when I walked though the backyard to the pool. I had to chose one from Sennheiser Presence, Plantronics Voager Legend, and Jabra Talk 45. 25 inch sole so wont wear down these slippers any time soon. These shelves are great. They are practically ancient in the world of technology (okay they are ancient in the world of technology) but I really dont want to buy another ipad yet. I purchased three products to compare that claim to improve this situation:-Earhoox 2. 5 second audio delay (Netflix, Prime, YouTube, etc. Shipping was pretty fast and Im happy with my purchase. Was it the cheapest wire I could find on Amazon and in the few stores I looked at prior to making this purchase? Yes.
