This was a pilot study utilizing hospital-based walking trials to compare two footwear conditions. Two pairs of identical therapeutic shoes were ordered for volunteer claudicant subjects. One pair was adapted with a specifically designed three-curve rocker sole. Volunteer claudicant subjects (n = 8, mean age 66 +/- 9.9 years) with stable pain-free distances of 10-400 meters to calf claudication pain were recruited into the study. Walking trials were used to compare differences in both the pain-free distance to claudication and the intensity of the calf pain once claudicating exhibited by each subject while walking separately with the two footwear conditions during the same clinical session. The results demonstrated that claudicant pain-free walking distance was increased, and the intensity of claudication calf pain reduced when walking with the rocker-soled in comparison with baseline. A specifically designed rocker sole has the potential to offer a reduction in the intensity of calf pain experienced by claudicants. A more extensive study is planned to determine the efficacy of this new footwear adaptation when the footwear is worn for extended periods.
