Superfeet Run Support Low Insoles

The Superfeet Run Support Low Arch insoles (formerly known as Superfeet Carbon) are designed for hikers and trail runners with low arches, commonly referred to as flat feet. Superfeet has long been recognized as a leading brand in the insole industry, offering a wide range of products tailored to specific foot types and activities. The Run Support Low Arch insole model provides targeted support, cushioning, and stability for hikers and runners who require or want more support than the standard foam inserts typically found in most trail runners and hiking shoes.

Superfeet Carbon Renamed

The Superfeet Run Support Low Arch insoles feature a relatively thin profile, ensuring a comfortable fit in most trail running shoes without causing tightness or discomfort. These insoles are the new name for Superfeet Carbon, which was the insole formerly used by hikers and runners to replace the foam insoles found in trail runners. Many retailers are still trying to sell off their old Superfeet Carbon insole inventory and use the new product name to sell you the old insole, when in fact, the new product is different and improves on the old.

When in doubt, my advice is to buy the Run Support Low version directly from Superfeet, which offers free shipping and a 60-day money-back guarantee, even if you’ve worn or trimmed the insoles. 

Design and Construction

A key feature of this new Run Support Low Arch insole is its reinforced stabilizer cap, located at the heel. This cap not only adds structure to the insole but also provides much-needed stability for those whose feet might otherwise roll inward (overpronation) due to low arches. (The sides of the old model were curved – the new model has more perpendicular sides, offering better stability.) The heel cup is deep and supportive, cradling the heel firmly and helping to distribute impact forces more evenly. This is particularly beneficial for hikers and runners who are prone to heel pain or plantar fasciitis.

The mid-layer of the insole provides moderate cushioning using Superfeet’s proprietary foam. While not overly plush, it strikes a balance between comfort and responsiveness, allowing for good ground feel without sacrificing protection. The arch support is subtle yet effective, designed to provide gentle guidance rather than aggressive correction. This is crucial for low-arched hikers and runners, as excessive arch support can cause discomfort.

Fit and Comfort

One of the biggest strengths of the Superfeet Run Support Low Arch insoles is their fit, which is contoured to match the natural shape of a low-arched foot. When inserted into a trail runner or hiking shoe/boot, they sit flat and do not raise the arch too high, which could otherwise lead to pressure points.

During use, the insoles feel supportive without being intrusive. The heel cup securely anchors the foot, while the gentle arch contour provides consistent support. Hikers and runners with flat feet often struggle with fatigue and aches after prolonged periods of activity, but these insoles help alleviate these issues by promoting better alignment and reducing strain on the plantar fascia and surrounding structures.

Performance

In real-world scenarios, the Superfeet Run Support Low Arch insoles provide stable, unobtrusive support over various surfaces. You don’t even know they’re there. On trails or uneven terrain, they help maintain proper foot alignment, reducing the risk of rolling an ankle or developing overuse injuries.

One notable aspect is how they improve overall shoe fit. Many runners with flat feet find that standard shoe insoles do not offer enough support, leading to their feet sliding around inside the shoe. The Superfeet insoles address this by locking the heel in place and preventing excessive movement, which translates to better control and efficiency.

Durability

The materials used in the Run Support Low Arch insoles are robust, resisting compression and breakdown. The top fabric remains intact without peeling or excessive wear, and the foam retains its cushioning properties over time. Many users report that a single pair can last through multiple pairs of shoes, making them a cost-effective investment.

Who Should Buy Them?

The Superfeet Run Support Low Arch insoles are best suited for hikers and runners with low arches or flat feet who experience discomfort or instability during medium to long hikes. They are also a good option for those recovering from plantar fasciitis or who have a history of overuse injuries related to poor foot mechanics. Hikers who prefer a more minimalist insole or those with very high arches may find them less suitable.

Conclusion

The Superfeet Run Support Low Arch insoles deliver on their promise of support for low-arched runners. They combine thoughtful design with reliable performance to help reduce fatigue, prevent pain, and enhance comfort during runs. While no insole can solve every foot problem, these come close for those with flat feet looking for a supportive yet unobtrusive solution. At their price point, they represent excellent value given their targeted benefits. For hikers struggling with low arch issues, these insoles are definitely worth considering.
