Summary
Masai Barefoot Technology (MBT) shoes significantly alter plantar pressure distribution. These shoes reduce pressure on the midfoot and heel, shifting it towards the toes for improved comfort and gait.
Area of Science:
- Biomechanics
- Podiatry
- Orthopedics
Background:
- Footwear comfort relies on plantar pressure redistribution.
- Insoles can offload metatarsal heads.
- Masai Barefoot Technology (MBT) shoes offer a novel curved sole design for pressure management.
Purpose of the Study:
- To evaluate the impact of MBT shoes on gait patterns.
- To compare plantar pressure distribution between MBT shoes and traditional training shoes.
Main Methods:
- Normal subjects walked in both flat-soled training shoes and MBT shoes.
- An in-shoe electronic system measured plantar pressures and sole contact area.
- Pressure data was collected from four defined foot regions.
Main Results:
- MBT shoes reduced peak midfoot pressure by 21% and heel pressure by 11%.
- A 76% compensatory increase in toe pressure was observed with MBT shoes.
- A significant shift in pressure distribution towards the forefoot occurred.
Conclusions:
- MBT shoes alter plantar pressure distribution by reducing load on the midfoot and heel.
- This redistribution may enhance footwear comfort and affect gait biomechanics.
- Further research is warranted to explore clinical implications.
