Barefoot training, a practice of walking, running, or balancing barefoot or in thin, flexible shoes, aims to strengthen foot muscles that supportive shoes leave underused. Several trials show modest foot-strength gains; most found no balance gain, and none tested falls. Quick switches often cause calf, shin, and Achilles soreness; even gradual ones can stress forefoot bones. It is unsuitable for people with diabetes-related loss of foot sensation. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Protective sole sensation (10-g monofilament test) | Sensation felt at all tested sites | Safety check: loss stops barefoot use |
| Toe-flexor strength (handheld or plate dynamometer) | No established target; track change from own baseline | Expected to change: rises with training |
Cadence: Daily sole inspection during the first 3 months; strength and balance retesting at 4 and 8 weeks, then every 6 to 12 months; sensation testing yearly with diabetes, or sooner if numbness appears; weekly pain ratings during any running transition
