Where these two actually differ

  • We flag Azo dyes (carcinogenic dye intermediates), Residual manufacturing chemicals or finishes and Elastane degradation and microplastic shedding on the New Balance and not on the Puma.
  • We flag Azo dyes, Formaldehyde resins (finishing agents) and Microplastic shedding on the Puma and not on the New Balance.
  • The New Balance is nylon and elastane blend where the Puma is Cotton/polyester blend socks, no waterproofing, 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.
