CALCULATED VALUE

AUDITED STANDARDS

Peer-reviewed operational procedures executed by certified field specialists.

CLINICAL AUDIT

Determining shoe toe box constriction without complex radiological imaging.

01. Remove original factory insole from shoe and place flat on hardwood floor.
02. Step firmly onto insole with full bodyweight; spread toes naturally.
03. If big toe or pinky overhangs insole edge by >1mm, footwear is clinically pathological.

REHAB PROTOCOL

Strengthening abductor hallucis to pull the first metatarsal head medially.

01. Place foot flat on ground in bare feet; keep heel and balls of toes firmly rooted.
02. Draw ball of big toe toward heel without curling toes, elevating the medial arch.
03. Hold isometric tension for 8 seconds; repeat 10 reps per foot twice daily.

TRANSITION PROTOCOL

Safely transitioning Achilles tendon and plantar fascia without overuse tendinopathy.

01. Weeks 1-2: Wear wide-toe zero-drop shoes 2 hours per day for indoor walking only.
02. Weeks 3-6: Extend to daily errands; perform calf eccentric drops on stair edge daily.
03. Week 7+: Full transition to zero-drop footwear across all sports and athletic running.
