Enrollment: 20
Sex: ALL
Minimum age (years): 18
Maximum age (years): 50
Standard ages: ADULT
Accepts healthy volunteers: no
Observational model: CASE_CROSSOVER
Time perspective: PROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: regular runners with functional standing equine

Brief summary: 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.
