Is Barefoot more economical ?

Researchers at England’s Northumbria University analyzed the gait and oxygen uptake of 18 recreational and elite runners performing a series running tasks both barefoot and shod.

Dr. Michael Wilkinson, lead researcher and avid barefoot runner determined the following in their study:

- a significant saving in energy from taking off running shoes

- mechanical differences in the foot strike patterns (shod runners did more heel strike, unshod were more midfoot striking)

- there were immediate foot strike changes in previously shod  runners who suddenly changed to unshod foot strike

- there is less oxygen use during barefoot running compared to running shod at the same speed. Hence improved running economy.

Characteristically, skilled unshod runners have a distinctive running gait utilizing:

- mid-foot landing

- shorter stride lengths

- faster stride rates

- reduced ground contact time

- lower impact force and loading rates which dampens injury inducing forces

- reduced oxygen utilization. The 6% improvement in economy was the same as that previously reported after a nine-week training program for shoe-wearing runners, who also enjoyed a 3% improvement in running performance.
