Frequently Asked Questions
Will these insoles fit my running shoes without trimming?
PowerStep Pinnacle Maxx insoles are sold to fit by shoe size and typically don't require trimming. Because they have a thicker profile, check fit in your shoe — if your shoes are already snug, the added height can reduce toe-box space.
How long before I notice improvement for plantar fasciitis or overpronation?
Many users report reduced pain within days, but a short transition period of a few hours per day is often recommended while your feet adjust. Consistent use over 2–6 weeks usually shows clearer gait and pain improvements.
Are these insoles durable for daily running?
The Pinnacle Maxx line uses dual-layer EVA and a firmer shell designed for repeated use; they’re durable for daily walking and recreational running. Heavy, high-mileage runners may see wear sooner and should monitor cushioning breakdown to know when to replace them.
