The science of fit
Why fit matters.
For your run
Better fit improves your running performance.
How a shoe holds your foot can influence how you run. A trail study found better fit ratings and slightly faster running with a different closure.

For your foot health
Better fit supports foot health.
More room isn’t always a better fit. In walking studies, oversized shoes increased pressure and sideways forces under the forefoot. Loose lacing increased the load on the toes.
