Confluence Running
Our take
Our first look: compare the R1 for long road outings when adjustable forefoot volume matters. Its lower stack distinguishes it from C1. Use a trail model when the route needs deeper tread.
Fit before category
Fit & feel
TUNEDFIT adjusts forefoot and midfoot tension independently. Test heel security without tightening the toe area excessively. Recheck the fit in the socks you expect to wear for your longest runs.
We fit shoes against your foot shape, width, comfort, movement and intended use—not just a label like “neutral” or “stability.”
How the shoe works
Technology & ride
LightCELL cushioning combines with ZeroSag inserts. The R1 uses a CPU outsole, while R1R substitutes rubber and adds weight.
