[15:22] Recap – 4 things

1. Friction is NOT rubbing
2. Shear is the stretching
3. Shear peaks in a state of static friction
4. Biphasic shear event

[19:22] Preventing plantar forefoot blisters

• [20:26] Reduce bone movement
• [22:11] Reduce friction force (by reducing pressure)
• [23:50] Reduce friction force (by reducing the coefficient of friction)
• [25:24] Absorb shear
• [26:11] Spread shear load
