The idea of prioritizing active strengthening over passive support via orthotics rests on a solid scientific foundation. A controlled study by Ridge et al. (2019) demonstrated that daily walking in minimalist shoes strengthens foot muscles just as effectively as targeted resistance exercises. Furthermore, a meta-analysis conducted by Hoang et al. (2021) confirms that physical exercise, whether alone or combined, is more effective in the long term for arch comfort than orthotics alone. Nevertheless, the assertion that orthotics resolve nothing is an exaggeration, as they remain very useful temporary assistive tools for quickly reducing fatigue during intense exertion. For its part, the specific efficacy of toe spacers in correcting foot collapse lacks direct clinical evidence, relying instead on expert opinion or research focused on the mechanical alignment of the toes. A very gradual transition remains essential to accustom the foot to this freedom of movement without the risk of creating new tensions.

What the graded evidence says

Evidence
B
Effect
foot muscle size and strength after minimalist-shoe walking vs targeted foot exercise vs control — 8-week RCT (n=57 runners): minimalist-shoe walking increased foot muscle size and strength significantly and comparably to a dedicated foot-strengthening program; no change in controls
Measured on
healthy adult runners

What’s uncertain

Evidence comes from a single well-controlled trial in runners. The strengthening effect is real, but a rushed transition can cause overload injuries, so progress gradually.
