They also wirelessly charge in the case. I highly recommend this. It is firm enough to not fold up on standing, offering easy placement of my feet without using hands. I wish Amazon had them in white and maybe a charcoal color, Id get those too. The rear wheel is resting on the floor. You can see the image fairly clearly, but I certainly would not classify it as HD. They are well made and have open toes which is perfect for summer. The only issue I?ve had is the carabiner could stand to be a bit higher quality. helps tolerate bit of plantar fasciitis. To be honest, Id only bother with these when flying (or maybe long train/car journeys - Ive tested them on a train with less pronounced effect than on a plane).
