Definitely very happy, and they look just like leather without being that. I usually wear a 9 and I own one pair in a 10, and another in an 11. Lo sto usando e mi ci trovo benissimo. When she tries to wear them down the slide, the heel of the shoe/sock is also anti-slip. I use alarm clock apps and as we all know you have to charge your device while the app is in use because it drains your battery. I can sleep with it while on my side and its all good. Also, unlike the LS30, when the battery gets low, it simply provides an infrequent warning about it, so theyre still perfectly usable in that state. Great Sound, but the left speaker went out a few days ago. I picked up a pair of knock-off Birk Arizona EVA sandals at Kohls a few years ago and they ended up being one of my favorite pairs of sandals Ive ever owned. So I am using it but its not my favorite spice rack.
