Description
Long shifts standing, a marathon training block, or legs that simply feel heavy by evening: compression boots are one way people wind down. The Air Relax Pro AR-4.0 is a full system, with a control unit, a pair of leg sleeves and a case to carry it all.
How the boots work
Each leg sleeve has six overlapping, seamless chambers. A pump in the control unit fills and empties them in one of four patterns: sequential, progressive, drain and overlay. You can also choose which chambers run. Air Relax describes the medical-grade pump as 60% stronger than other recovery systems, and the system is FDA-cleared.

Taking it on the road
Dual voltage means it works in most countries. An optional power bank (5,700 mAh / 83.2 Wh Samsung cells) gives up to 3 hours away from an outlet, but it is sold separately. The 38L carrying case holds the control unit (about 10.4 × 7.7 × 7.1 in), sleeves, hoses, AC adapter and manual.
Before you use it
Air Relax advises consulting your medical practitioner before use and reading the contraindications. This matters more than usual with compression: if you have a history of blood clots, heart or circulation problems, or one leg that is suddenly swollen, red, warm or painful, get that checked before any compression device goes on. HSA/FSA details are available from Air Relax.
