Run 619 4.5mm Firm Shoe Inserts | Zero Drop | Foot Forming | Traditional Shape

Multiple Uses: Our firm, 4.5mm Run 619 insoles can replace factory insoles, fit under custom orthotics, or help fill extra space in oversized shoes and boots, provided there is room. Ideal for runners, walkers, hikers, and anyone constantly on the move. Precise Fit and Function: Our flat 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, shoot us an email at hello@run619.com and we’ll get you sized up in a jiffy. Zero Drop Profile: Our shoe insoles
