Frequently Asked Questions
Do Dr. Scholl's insoles work for plantar fasciitis?
Short-term, yes. The Heavy Duty Support gave immediate comfort with no break-in and a usable 16 mm arch. The problem is durability: the foam compressed visibly after 35 days in our test, so the support fades in about a month.
Dr. Scholl's vs PowerStep for plantar fasciitis?
PowerStep Pinnacle has a firmer 18 mm arch and showed zero compression at 42 days, so it lasts far longer. Dr. Scholl's Heavy Duty is about a third of the price and fine as a starter or backup, but budget to replace it every 4-6 weeks.
How long do Dr. Scholl's insoles last?
About 5 weeks of daily wear before the foam noticeably flattens, based on our 42-day test. If you're on your feet all day, expect less. Firm shell insoles like Superfeet and PowerStep hold their shape for months by comparison.
