These are compression boots from Sharper Image. They work by using air to compress your legs and massage them. There are 5 program settings, Pulse, Gradual, Sequence, Zones and Manual. There is also a pressure setting. A timer is also an option. There is no box. Works wonderfully and helps with those leg pains. Length of boot from top to bottom 38in. This was lightly used and more new than anything, control box shows a few scuffs but nothing at all that affects functionality.
