Where these two actually differ
- We flag Azo dyes in fabric blend and Formaldehyde resins in fabric finishing on the Powerstep and not on the Spenco.
- We flag Foam degradation and microparticle shedding, Adhesive or bonding agent residues and Mold or bacterial growth if not maintained on the Spenco and not on the Powerstep.
- The Powerstep is EVA foam, gel, fabric blend where the Spenco is Foam, rubber, textile composite insole, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
