Start with Your Comfort Needs
If you spend long hours on your feet in work boots, the right insole can make a noticeable difference in how your feet feel at the end of the day. Insoles aren't one-size-fits-all, so matching the cushioning and support to your activity and foot shape is key. This guide walks through what to look for and how two KEEN insole options compare.
Two KEEN Insoles for Work Boots
- Men's Utility K-20 Cushion Insole | Black: Medium arch support, shock-absorbing pads and a full-length layer of high-rebound foam help fight foot fatigue for long days on your feet. If you need a balance of arch support and cushioning without a high arch profile, this insole is a practical choice for general work boot use.
Men's Utility K-20 Cushion Insole | Black - Men's Outdoor K-20 Plus Insole | Black: Full-length foam cradles every step, while the anatomic heel cap provides support and stability. The anatomic heel cap adds extra stability around the heel, which can help if you experience heel slippage or want a more secure fit inside your boot.

How to Choose Between the Two
Both insoles share the same men's sizing: Small (6.5-8), Medium (8.5-10), Large (10.5-12), X-Large (12.5-14). Your decision comes down to the type of support you need.
- For all-day cushioning with medium arch support: The Men's Utility K-20 Cushion Insole uses shock-absorbing pads and high-rebound foam. It's a solid option if you want a familiar, balanced feel that fights foot fatigue without a dramatic change in boot fit.
- For added heel stability and full-foot cradle: The Men's Outdoor K-20 Plus Insole features an anatomic heel cap that wraps the heel for extra support. If you often feel your foot shifting inside your boot or want a more locked-in heel fit, this design helps.
Fit and Sizing Tips
Both insoles are sold in size ranges, not exact shoe sizes. Check your boot's current insole length or your usual shoe size against the size chart: Small (6.5-8), Medium (8.5-10), Large (10.5-12), X-Large (12.5-14). If you're between sizes, consider the larger range and trim if needed (the supplied information does not confirm whether these insoles are trimmable, so check the product packaging). Replace your insoles when they lose their shape or cushioning, typically after several months of daily wear.
