Run 619 Original Flat Insoles | Zero Drop | Firm | Traditional Shape | Regular Width | 3mm

Multiple Uses: Our thin, flexible, flat inserts can replace factory insoles, fit over custom orthotics, provide a thin layer of firm cushion or provide additional support in tightly fitting shoes and boots, ensuring minimal bulk. Perfect for runners, walkers, hikers, and anyone constantly on the move. Precise Fit and Function: Our flat shoe insoles, suitable for both men and women, are available in eight sizes to ensure a more accurate fit. They can also be easily trimmed with scissors for even greater precision. Perfect for hiking, running, walking, or a long work shift. Updated Sizing Guidance (July 2025): Our insoles haven’t changed, only our suggested sizing. Based on customer feedback, we fine-tuned the chart (most adjustments are about half a size). If you’ve ordered before and want the same fit as your last pair, match by the insole length from your previous order to our sizing chart, not by shoe size. If all else fails, contact us and we’ll get you sized up in a jiffy. Zero Dro
