You’re five miles into a beautiful ridgeline hike, the views are epic, but a familiar, sharp pain is radiating from your heel. That stabbing sensation of plantar fasciitis can turn a dream day on the trail into a painful limp back to the car. The good news is that you don’t have to hang up your boots; the right aftermarket insole can be one of the most effective tools for managing foot pain and keeping you on your feet.

How Insoles Combat Plantar Fasciitis on the Trail
When you’re hiking, your feet are under constant stress from uneven terrain, added pack weight, and thousands of repetitive impacts. For someone with plantar fasciitis, this is a recipe for inflammation. The plantar fascia, a thick band of tissue connecting your heel to your toes, gets overstretched and strained, leading to that characteristic heel pain.
A good hiking insole fights this in three key ways. First, it provides structured arch support to prevent your arch from collapsing with every step, which reduces the strain on the fascia. Second, a deep, cushioned heel cup absorbs shock and cradles the heel’s natural fat pad, providing both comfort and stability where the pain is most acute.
Finally, many insoles offer a degree of motion control. They help correct biomechanical issues like overpronation (where the foot rolls too far inward), which is a common contributor to plantar fasciitis. By guiding your foot into a more neutral alignment, the insole distributes pressure more evenly and reduces stress on that inflamed tissue.
Superfeet TRAILBLAZER for Heel Lock and Stability
Imagine scrambling down a steep, rocky decline where precise foot placement is everything. If your foot is sliding around inside your boot, even slightly, it creates friction and instability. The Superfeet TRAILBLAZER is engineered specifically to combat this with its exceptionally deep and structured heel cup.
This design locks your heel in place, preventing slippage that can aggravate the plantar fascia. It also positions the soft tissue beneath your heel bone to maximize natural shock absorption. An EVOLyte carbon fiber stabilizer cap provides responsive, weight-defying support that won’t collapse under the load of a heavy multi-day pack.
The tradeoff here is volume. The TRAILBLAZER is a high-volume insole, meaning it takes up significant space inside your footwear. It’s a perfect match for traditional hiking boots with removable sock liners but could be too bulky for snugger, lower-volume trail runners.
SOLE Active Thick for Custom-Molded Arch Support
Do you find that generic, off-the-shelf arch shapes never seem to hit your foot in quite the right spot? The SOLE Active Thick insole addresses this with its signature moldable base. You can either gently heat them in an oven for a quick custom fit or simply wear them for a few days as they adapt to your unique foot shape.
This custom support is a huge benefit for plantar fasciitis, as it ensures the entire length of your arch is supported, preventing the fascia from overstretching. The "Thick" version uses a dense 3.2mm foam layer, providing maximum shock absorption for long days carrying a heavy pack over hard-packed trails. Its zero-drop platform also promotes a natural foot posture.
Be mindful of the "Thick" designation. Like the Superfeet, this is a high-volume insole designed for roomy hiking boots or work boots. If you’re hiking in low-profile footwear, consider their "Medium" or "Thin" versions to get the same custom-molding benefit without overcrowding your shoes.
Oboz O FIT Insole Plus for All-Around Cushioning
For the weekend warrior or day hiker who wants a straightforward, effective upgrade from their boot’s flimsy stock liner, the Oboz O FIT is a fantastic starting point. It’s the insole that comes standard in Oboz footwear, and it’s popular as a standalone product for good reason. It delivers a well-balanced blend of features without being overly aggressive in any one area.
The design features a medium-height arch and a supportive heel cup that work for a wide variety of foot types. Dual-density EVA foam pods are placed in the forefoot and heel for targeted cushioning where you need it most. It provides a noticeable improvement in both comfort and support without a long break-in period.
This insole isn’t a highly corrective, medical-grade device. Instead, it’s a workhorse designed for all-around trail performance. It’s an ideal choice if you’re just beginning to explore aftermarket insoles and need reliable cushioning and support for everything from local park loops to moderate overnight trips.
Currex HikePro for Dynamic Support and Flexibility
If you hike in trail runners or lightweight boots and value feeling connected to the trail, a rigid, board-like insole can feel restrictive. The Currex HikePro is built on a philosophy of dynamic support. It’s designed to flex with your foot’s natural motion, providing support without hindering movement.
This flexibility is great for hikers who want arch support but don’t need aggressive motion control. Instead of a hard plastic shank, it uses a semi-rigid plate that moves with you, reducing fatigue over long miles. It also features targeted PORON cushioning in the heel and under the ball of the foot for excellent shock absorption.
A key advantage of Currex is that they offer their insoles in three different arch profiles (High, Medium, and Low). This allows you to get a much more personalized fit right out of the box. This is an excellent choice for the fast-and-light crowd or anyone who finds traditional insoles to be too stiff.
Powerstep Pinnacle Maxx for Overpronation Control
Sometimes, heel pain is just one symptom of a larger issue: overpronation. If you notice your ankles rolling inward and uneven wear on the inside edge of your boot soles, your foot mechanics could be putting massive strain on your plantar fascia. The Powerstep Pinnacle Maxx is specifically designed to correct this.
Its defining feature is a firm, supportive shell with a slightly angled heel post. This combination provides powerful motion control, actively preventing your foot from rolling too far inward. This alignment can relieve stress not only on your fascia but also on your ankles, knees, and even hips.
This is a semi-rigid, corrective insole, and it feels like one. While it has a comfortable foam top layer, the underlying structure is firm and uncompromising. It’s a specialized tool that is incredibly effective for overpronators but may feel too aggressive for hikers with a neutral gait.
Tread Labs Pace for Extra-Firm, Medical-Grade Arch
For the thru-hiker or serious backpacker who measures trips in weeks, not days, durability is paramount. Most foam insoles will "pack out" and lose their supportive structure after several hundred miles. Tread Labs Pace insoles are built for the long haul with a unique two-part system.
The core of the insole is a medical-grade, molded polypropylene arch support that is virtually indestructible and guaranteed for life. This provides unwavering, extra-firm support that won’t collapse under the weight of a heavy pack, mile after mile. The top cover is a replaceable foam layer, so you can refresh the cushioning without having to buy a whole new insole.
This is a system for those who prioritize structural integrity over plushness. The Pace is available in four distinct arch heights, making it critical to select the right one for your foot. It’s the ultimate choice for hikers who need maximum, long-term support and see their gear as a long-term investment.
Choosing Your Insole: Arch Height, Volume, & Fit
With so many options, how do you choose? Focus on three simple factors to narrow down the field and find the right insole for your feet and your boots.
First is Arch Height. This is the most important factor for plantar fasciitis relief. To find yours, perform a "wet test": get your feet wet and stand on a piece of cardboard. A full, flat footprint means low arches; if you see only your heel and the ball of your foot, you have high arches; anything in between is a medium arch. Match your insole’s arch profile to your foot type for proper support.
Next, consider Volume. This refers to how much space the insole takes up in your boot. You must match the insole volume to your boot’s volume.
- High-Volume Insoles: Best for traditional backpacking boots and footwear with lots of interior space.
- Mid-Volume Insoles: The most versatile, fitting most standard hiking boots and shoes.
- Low-Volume Insoles: Designed for snug-fitting trail runners, approach shoes, or minimalist boots.
Finally, nail the Fit. Use your boot’s original liner as a template to trim your new insole to the perfect size. When you place it in your boot, ensure it lies completely flat with no bunching, and that your heel sits securely and comfortably in the heel cup. A poorly fitting insole can cause more problems than it solves, so take the time to get it right.
Finding the right insole can feel like a complex puzzle, but it’s one of the most powerful changes you can make for trail comfort. Don’t let the fear of gear perfection keep you indoors. Start with an insole that matches your arch and boot type, make small adjustments, and get back on the trail, because the best gear is the gear that keeps you out there.
