Overview
Sliding into most shoes without trimming, this Dr. Scholl's Custom Fit insert adds three layers of shock absorbing cushioning, adaptive arch support and a soft top cloth. It is one of a range matched to arch type, body weight and shoe size.
Matched support and slip-in fit make it easy to move between shoes, even ones with fixed insoles. It is a specific model in a matched range, so the wrong match may not suit your foot.
Who it's for
Walkers, runners and people standing at work get targeted support that moves between shoes. People needing prescription orthotics should see a podiatrist.
Pros and cons
- Three cushioning layers

- Fits shoes with fixed insoles
- Moves between shoes
- Specific match model
- Toes not cushioned
- Firm support needs adjustment
Performance notes
Support comes from the adaptive arch layer, which spreads pressure and absorbs shock from heel to midfoot. The shock-absorbing base cushions impact on hard ground. The shorter length leaves room for toes in tighter shoes.
