How Flux works.

The science of feeling light on your legs again — in plain English.

Your calves are your second heart.

Gravity pulls fluid down. When you stand — or sit — for hours, the calf muscles that normally pump fluid back up your legs go quiet. Fluid pools, and by the end of the day your legs feel heavy, tight, and tired.

That heaviness isn't in your head. It's hydraulics. Walking and bending act like a second heart for your lower body; long, still hours switch that pump off.

Sequential compression: the muscle pump, mechanized.

Tempr Flux inflates six chambers in sequence, foot to thigh — the direction your body wants fluid to move. It's the same approach physiotherapy settings have relied on for decades.

Flux delivers that clinical-grade pressure without cords, hoses, or clinics: the pump and battery are built into the boots, and every session runs a complete foot-to-thigh cycle in 15 minutes.

Good questions

How is this different from compression socks? +

Socks apply static pressure — the same pressure all the time. Tempr applies dynamic pressure that moves up your leg in sequence, foot to thigh, mimicking the muscle pump your calves stop doing when you're on your feet all day. Different mechanism, different result.

I'm pregnant / I have varicose veins / I have a circulation condition. Can I use Flux? +

Tempr Flux is a wellness device, not a medical treatment. If you have a medical condition or you're pregnant, talk to your doctor before using compression products of any kind.
