Overview
Spenco builds the Polysorb Cross Trainer insole from layered foams: polyurethane for arch and heel support, a Spencore layer and heel plug for shock, and EVA under the forefoot. A four-way stretch top cloth reduces blisters and odor.
Worth it for high-impact sports where heel strikes and forefoot landings hurt, since the cushioning is layered where impact lands. It fills the full length of the shoe, so snug shoes may feel tight.
Who it's for
Made for running, walking, cross training and long days on the feet in athletic shoes. People looking for rigid orthotic correction or slim inserts for tight shoes should choose a different style.
Pros and cons
- Layered shock-absorbing foams
- Arch and heel support
- Anti-blister stretch fabric
- Odor control top cloth
- Trimming guidance not listed
- Adds height inside snug shoes
Performance notes
Shock absorption comes from the Spencore layer and heel plug compressing on impact, while EVA in the forefoot returns energy at toe-off. The polyurethane arch adds support without a rigid shell, which suits flexible athletic shoes. Fit depends on the shoe's volume, since the insole fills the full length.
