After exclusion of articles that did not meet the inclusion criteria, the remaining articles were selected to be fully read and those that did not investigate overload due to the use of blade-£185.86£185.86. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results.
