Two-point discrimination critique

Nike says this new "brain-first" shoe can unlock focus and performance but does the science hold up, or is it just brilliant marketing?

In this episode of the The MOVEMENT Movement, Steven Sashen speaks with Courtney Conley, Jay Dicharry, Dr. Irene Davis, and Dr. Emily Splichal who break down Nike's new sensory-focused shoe and the bold claims behind its "mind tech," from two-point discrimination to "amplifying" what your feet feel. The conversation challenges whether thick cushioning and widely spaced pods can truly enhance sensory input — and why novelty and instability can be mistaken for real performance gains. You'll also hear the bigger takeaway: how to think about foot strength, sensation, and movement so you're not buying a shortcut that quietly makes you weaker.

Key Takeaways:

→ How Nike's two-point discrimination explanation doesn't match the large, spaced pods on the shoes.

→ How Nike's design appears to ignore the toes, which is a major sensory area.

→ Why the thick, soft cushioning may mute sensation, contradicting Nike's claim.

→ Why claiming a shoe has both barefoot benefits and more protection is misleading.

→ How Nike's creation of a "minimalist shoe" sparks mainstream awareness of foot sensory science and education.
