About this study
Official title: Footwear Difference in Sports Use in Runners With Functional Equinus: Observational Study
Observational study on Nimbus shoes for daily training with 8mm drop and designed for heavier than normal weight. Shoe weight is 300g with highly structured buttress and upper with internal heat-sealed midfoot for greater lateral stability. This is a Novablast shoe with a mixed profile for training and competition with 8mm drp and higher midfoot compression range with less lateral containment.
