North Park's dedicated running specialty shop since 2013, Milestone Running Shop operates from 2545 El Cajon Blvd and fits every customer through a video gait analysis before recommending neutral, stability, or motion-control footwear. Runners recovering from plantar fasciitis, shin splints, or IT-band strain often arrive on referral from providers like RISE Physical Therapy, translating clinical gait findings into corrective shoe selections. The store stocks performance footwear, race-day apparel, hydration gear, and nutrition products, and hosts a weekly run club that loops through North Park's residential streets. Triathletes and multi-sport athletes cross-shopping cycling components head to Stubborn Goat Bike Shop and Ski Service on 30th Street for wheel and frame fitting after dialing in their running shoes. The shop's most technical service is its full biomechanical fitting protocol, capturing treadmill video of the customer's stride and mapping pronation patterns to match each runner with the optimal support category and shoe model for distances from 5K through ultramarathon.
