Q. If unsure, should I order a size up or down?
A. OLLO’s fit snug. Always order a size up if you are an in between size.
Q. What is the orange insole for? How do I use it?
A. The orange insole that comes with your OLLO’s has two purposes. One is to provide an extra level of impact cushioning. The other is to create a more snug fit. Remove the main insole that is currently in your OLLO’s, Place the orange insole cleanly inside your OLLO’s and put the main insole back in your shoes on top of the orange insole.
