It’s an interesting theory, but as someone with horrendous ankles (courtesy of high arches — we’re talking in the absurd range), I lack balance due to repeated injury. I’ve torn ligaments and tendons in both ankles and gone through surgical repair twice. While physical therapy and exercise have helped me regain mobility and SOME balance, attempting the exercise leaves me falling within a blink as my ankles wobble all over the place. Hate to think my poor anatomy foretells an early death.
