Silicone tread

Dual-durometer moulded silicone tuned for hardwood, stone and quiet footfall.

Cutaway of the outer foot, showing the tan over-moulded heel pad, a geometric titanium lattice mid-sole, the chevron-patterned silicone tread skin and the splined ankle drive coupler at the top. Leader arrows mark four labelled parts.

The sole is moulded in 65-Shore-A silicone with a chevron tread tuned for hardwood and stone, then over-moulded with a softer 30-Shore-A heel pad for acoustic damping. Footfall sound at 1 m measures below 38 dBA — quieter than a barefoot human.
