Can anyone confirm that the Vizipro and standard model Endorphins are exactly the same except the the reflective upper?

The reason I ask is I have both models and both times I’ve worn the Vizipro model, I could barely walk the next day. I have also worn the Speed Vizipro and had the same issue. My current problem has been with the Tempus model.

The only thing I can think of is the Vizi’s need a break in period which still doesn’t make sense if it’s basically the same shoe. I’ve had three pair of Tempus and never had a problem until I tried the Vizipro model. Same with the Speeds. Had multiple pairs but never had a problem until the Vizipro
