0 connect seamlessly to my iPhone X, and my iPad Pro (2018 3rd gen). And the volume couldnt be made loud enough to enjoy music over the subway roar. I wear a size 9 and my feet are a bit wide, and these fit just beautifully. I got these on a bargain, but I definitely think that they are worth the initial price. Toes and heel are inside the shoe. They are durable with a sneaker-like sole and well made. The lip on the tote also added a little more security because it prevented the belly strap from potentially riding up. Sound is pretty good when wanting to listen to music discretely at the office and still hear dont around me. Read the description and look at the pictures. Nothing is 100% theft-proof but the locks seem sturdy enough to afford you some peace of mind.
