Athletic Series Sport Massaging Gel Insoles vs Pulse Performance Insoles: which is safer?

Where these two actually differ

• We flag Unspecified polymer coating leaching, Gel degradation and microparticle shedding, Moisture trapping and bacterial/fungal growth and Thermal instability and off-gassing on the Dr. Scholl's and not on the Powerstep.
• We flag Azo dyes in fabric blend and Formaldehyde resins in fabric finishing on the Powerstep and not on the Dr. Scholl's.
• The Dr. Scholl's is Gel compound with synthetic polymers, unspecified coatings where the Powerstep is EVA foam, gel, fabric blend, which is most of the difference in these two grades.
• The gap is 35 points, wide enough that this is not a close call, and the Powerstep is the one to buy.
• We are less certain about the Dr. Scholl's grade, at 35% confidence against 72%, because it discloses less.
