Does the list price include a pair?
We use the figure on the manufacturer page as published. Some pages list a pair; some list a single. Read the source line.
FitScout spec scores are our rubric, not Amazon ratings. List-price bands use manufacturer MSRP with a source and date. We do not print Amazon prices.
