Estimate your potential time savings when switching into the latest efficient carbon plated running shoes for your races
0 shoes in database
Running economy measures how efficiently you use oxygen at a given pace. Super shoes with carbon plates and advanced foams can improve this by 2-5%.
Distance factors: Benefits compound over longer distances. A marathon sees ~100% of the shoe's benefit, while a 5K sees ~70% and a mile ~50%.
Weight matters: Heavier runners typically see reduced super shoe benefits as the foam compresses more. Lighter runners (<55kg) get the full benefit, while heavier runners (90kg+) may see 60-70% of the advertised benefit.
Individual variation: Response varies significantly based on running form, pace, foot strike, and biomechanics. The confidence range reflects this uncertainty.

How we calculated this
The most efficient carbon-plated racing shoes based on published research
🧬 You can't put a single % on a shoe without testing the runner wearing it. These economy figures are averages from research studies — your personal response could be significantly higher or lower. Some runners gain 5%+ from a shoe while others gain almost nothing from the same model.
This calculator provides rough estimates based on published research and manufacturer claims. Individual results vary significantly based on:
💡 The only way to know your true response is to test the shoe yourself. Use these estimates as a starting point, not a guarantee. If a shoe doesn't feel right, the numbers don't matter.
