Pace and heart rate tell you how hard. Sol tells you how well. Every runner has habits — small inefficiencies that compound over thousands of steps. Sol picks up on these patterns early, in plain language.
Discover Sol →Sol sits inside your shoe — thin, unobtrusive, barely there. During your run it quietly tracks how your weight shifts, how your foot contacts the ground, and how your effort distributes across each stride. After your run, it surfaces simple, human insights. Not data. Signals.
Sol learns how you move —
quietly, precisely, over time.
Trim Sol to your shoe size and place it inside your running shoe, over your existing insole.
Go for your run exactly as you normally would. Sol works quietly in the background — no buttons, no interruptions.
Open the Sol app after your run. See a short, readable summary of how you moved — and what to watch over time.
Early access pricing. No charge until Sol ships. Cancel any time.
