Designed to support most medium to high arches without adjustment, these insoles also cushion impact and reduce friction to prevent blisters.

  • SpenCore™ layer cushions impact.
  • Moldable orthotic cradle provides balance and stability.
  • Low friction top cloth helps prevent blisters.

To Increase Arch Height: Heat orthotic in boiling water for two minutes. Using gloves to protect your hands, bend the orthotic to the desired shape. Allow the orthotic to cool. Remold if necessary.

Great Product at an Excellent Price

This is an excellent arch support. The price for this product at Holabird Sports is almost half of what I paid locally.

SUPERB! My Doctor recommended them (Spenco 3/4 arch support)

Spenco 3/4 arch support is an excellent product. I have used them for many years, after my doctor recommended them when I had a painful case of Plantar Fasciitis (& I had asked about "Dr" Scholls insoles) I'm on my feet all day, & they enable me to last. They make a big difference !!!

Not Worth a Dime

After careful molding and cooling 20 pounds would still collapse these things. Take two steps and they collapse and you feel like your walking on a flat piece of hard plastic . . . which you are. I big waste of money.
