I get paid to run. Barefoot-chi-Pose has been a revelation over the last two years. At 38 I’m finally injury free and running faster than ever. I seriously regret not taking it up decades ago.
The key technique is to take shorter, but quicker strides – 180/min is good. This way your calves are able to work more efficiently and hurt less.
I use Innov8 Baregrip 200 shoes for fell running and XC, Newtons on the road, VVF lace-ups for interval and treadmill stuff. However, most minimalist footwear is still too narrow for a perfect fit.
