What pressure should compression boots be set to?

WHERE THE NUMBER COMES FROM

Maia, Nakamura, Sarmento, Marcelino and Ribeiro pooled seventeen trials covering 319 participants in Biology of Sport (2024, 41(4) 263–275). The included studies were rated fair to good on the PEDro scale. Across them, the protocol that recurred was twenty to thirty minutes at roughly eighty millimetres of mercury.

What makes this worth knowing is not the number on its own. It is that Hyperice's own guidance for the Normatec 3 and Elite Legs also says twenty to thirty minutes. The independent literature and the manufacturer arrived at the same session length, and almost nobody puts the two side by side.

WHETHER YOUR DEVICE REACHES IT

• Normatec 3 Legs, Elite Legs, Elite Hips and Full Body — 40 to 110 mmHg across seven levels. The band sits in the middle of the range.
• Normatec Go — 40 to 200 mmHg. Reaches it easily and goes well beyond.
• JetBoots Prime — 25 to 100 mmHg in steps of 25. The 75 and 100 steps bracket the band; there is no 80 setting exactly.
• Hyperice X 2 Knee — 80 to 160 mmHg across five levels. Level one is 80 mmHg precisely.

WHY HIGHER IS NOT SIMPLY BETTER

One 2025 trial of 48 trained athletes found compression at 100 mmHg maintained muscle elasticity better at 48 hours than compression at 25 mmHg. That establishes pressure as a real variable rather than a spec-sheet flourish. It does not establish that more is always better, and no trial in the pooled set tested the top of the Normatec Go's 200 mmHg range for recovery.

The honest reading: get into the band, stay there, and treat anything above it as unstudied rather than superior.

WHEN TO JUDGE THE RESULT

Soreness benefit peaks around two days out. A 2017 meta-analysis of massage and delayed-onset muscle soreness put the effect at SMD −1.51 at 48 hours against −0.61 at 24. Measuring how your legs feel ten minutes after a session is measuring the wrong thing at the wrong time.
