Bought Next Percents in my regular size and they seem really snug around the middle of the foot. Are they supposed to be like that? The middle sole of the shoe is really narrow like it's going to bust at the seams. All the other nike shoes I've run in aren't like these including the racing flats, Almost want to exchange them for a 1/2 size up but I'm not sure if that's going to solve the narrow footbed issue.
Yes, I went up half a size over the 4%s (original and fly knit)
Are you in the Pink color? Nike is a big manufacturer and from the same shoe but different color they may use a different factory for a specific color run that does have a sizing variance.
Sometimes they're made in Vietnam, Indonesia, or China and a different country is slightly bigger/smaller. I had this experience with Pegasus 34s. You could wait for the new Hyperion Series or Endorphin from Brooks/Saucony...Also my current racer is Nike zoom fly SP(underrated) this has the same upper as next % and is only .7 oz heavier. The SP Compared to my Pegasus 34s was 1 full size small.
I used the same size. No issues. I wouldn't size up if not needed, it increases the shoe weight. I find the Next% a bit longer than the flyknit.
Does the midfoot feel narrow and really snug for you?
