EnerFlex Arch Support Insoles

Industrial-Grade Carbon Fiber Work Boot Insoles

Built for the guys who spend 12 hours a day on concrete, climbing steel ladders, and hauling gear. Your boots might be tough, but what’s inside them needs to work just as hard.

• Relentless Support for Long Shifts: Concrete floors take a massive toll on your body. These insoles deliver heavy-duty shock absorption from heel to toe, killing foot fatigue, knee pain, and lower back strain before it starts.
• Sweat-Defying & Breathable: We know how hot steel-toe boots get. The heavy-duty mesh top layer and premium PORON® foam wick away sweat and allow your feet to breathe, keeping you dry and comfortable from punch-in to punch-out.
• Custom Fit for Your Work Boots: Trim the edges to get the exact fit for your specific boots. The built-in flex point moves with you, giving you maximum support and flexibility whether you're crouching under a sink, kneeling on a roof, or operating heavy machinery.
• Fight Fatigue with Every Step: Stop bringing the job site home with you in the form of dead legs. The rebound cushioning acts like a shock absorber, taking the brunt of the impact so your joints don't have to. The flat, zero-drop design drops seamlessly into almost any work boot.
• Armor-Plated Core & Heavy-Duty Heel: Built with a lightweight but incredibly tough carbon fiber core that won't buckle or flatten under pressure. Combined with a load-bearing, honeycomb silicone heel pad, it handles the heavy impacts of jumping out of the truck bed or carrying heavy materials all day long.
