Run 619 Original Flat Insoles | Zero Drop | Firm | Regular Width | 4.5mm

Multiple Uses: Our firm, 4.5mm Run 619 flat 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, contact us and we’ll get you sized up in a jiffy.

Zero Drop Profile: Our flat insoles feature a traditional shape with a zero-drop profile and no arch support. These orthotics offer a lightweight, firm layer of neutral EVA, making them suitable for running shoes, walking shoes, work boots, hiking boots, or any footwear that accommodates shoe inserts. Note that these insoles do not feature a wide toe box. For wide toe box shoes, compare the forefoot width of your existing insole with the forefoot measurements on our sizing chart; length can be ignored. You may then trim the insoles to fit as needed.

Durable High-Density Foam: Crafted from closed-cell, firm EVA, our flat insoles are designed to alleviate discomfort on hard surfaces. The high-rebound material ensures lasting performance for months, whether you're running, walking, hiking, or on your feet at work.
