For some Nikes, particularly wider ones like the Resolve Plus, I take my normal size 9.5. But for narrow ones like Vapor Speeds, I take a 10. How do the Oscillates fit?
go up half to the 10's. The oscillates were made before Nike realized they were making shoes wide enough for 20% of the population and the other 80% either didn't buy them or played in shoes that don't fit.
