Massage Modes & Intensities
Choose from 6 distinct massage modes and 9 intensity levels to suit your preference:
- Auto Mode: Cycles through feet → lower calves → upper calves. Best for light circulation recovery and daily lower leg fatigue.
- Pinch Mode: Feet, lower calves & upper calves → feet & lower calves → lower calves & upper calves. Best for enhanced circulation and alternating compression after sitting or walking.
- Press Mode: Compresses all three zones (feet, lower calves, and upper calves) at once, then releases together. Best for intense compression and deep recovery after workouts.
- Foot Mode: Applies compression only to the feet, focusing on the soles.
- Calf Mode: Focuses compression on the lower and upper calves only.
- Cycle Mode: Feet → lower calves → upper calves → feet & lower calves → lower calves & upper calves. Best for gradual, full-lower-leg compression to boost circulation.

The massager offers 3-zone heat therapy with three adjustable levels:
- H1: Gentle Warmth (113°F)
- H2: Soothing Heat (122°F)
