Once installed, this product works great. these do the job! Lovely flip flips for my son. No need to worry about easy scratches. UPDATE: I?m keeping these. * Super easy to assemble. Oh and his southern twang got me every time. I contacted them and returned them easily and ordered an 8. Enough said! We previously tried Natives but they were not suitable for my child - too snug and not wide enough, not really adjustable.
