Do Cycling Insoles Actually Improve Power Output?

Insoles are one of the most discussed – and most underestimated – upgrades in cycling. The question is simple: do they really help you push more watts, or is it just marketing?

Where power is lost

Inside a stiff cycling shoe, every micro-movement of the foot costs energy. A collapsing arch, an unstable forefoot or uneven pressure distribution mean that part of your effort never reaches the pedal.

Why stability matters

A supportive insole keeps the foot aligned, the arch supported and the pressure spread out. That means less wasted motion, more direct power transfer and a cleaner pedal stroke under load.

What improves efficiency

• Stable foot position throughout the pedal stroke
• Even pressure distribution across the forefoot
• Reduced micro-movements under high load
• Better neuromuscular control over hours of riding

Conclusion

Insoles won't replace training – but the right pair removes losses you didn't even notice. For most riders, that's the most efficient upgrade per euro spent.
