Over the past few years, running shoe technology has boomed. Marathon running shoes are now faster and more comfortable than ever. With the boom in shoe technology, there are more options on the market than ever. How do you know which marathon running shoes to wear? This article delves into the science behind marathon running shoe technology and provides a guide on how to choose the best shoe for your next race.
What Should I Look for in a Marathon Running Shoe?
The most important feature of a marathon running shoe? Comfort while running. A 2021 meta-analysis in the European Journal of Sport Science found from four studies that comfortable footwear produced a statistically significant improvement in running economy compared to less comfortable footwear.
Cushioned shoes may be an optimal choice for a marathon running shoe. A 2022 randomized controlled trial published in Medicine and Science in Sports and Exercise concluded that highly cushioned shoes reduced oxygen cost and improved performance, even when muscle damage occurred. Muscle damage can be a limiting factor for performance in the marathon. While not every runner needs maximally cushioned shoes, marathon running shoes should have enough cushion to maintain performance even as muscle damage sets in.
You want a shoe that feels comfortable for you and provides enough cushion for the distance. For the marathon, this is likely a moderate to high amount of cushioning. Shoe trends reflect this: gone are the days of minimalist racing shoes. Carbon plate running shoes geared towards marathoners often feature high amounts of cushioning.
Should I Race My Marathon in a Carbon Plate Running Shoe?
Carbon plate shoes actually do help you run faster over long distances. A 2019 study in the Journal of Sports Science found that the Nike Vaporfly shoes improved running economy. The improved running economy was partially due to running economy being a significant factor in marathon performance.
Carbon plate shoes can work on both flat and hilly marathons. (Assuming it is a hilly road marathon, not a trail marathon.) A 2022 study in the Journal of Sports Science and Medicine found that carbon plate running shoes had a lower metabolic cost on uphill, flat, and down when compared to racing flats. However, it’s important to consider this study did not compare cushioned but non-plated shoes to see if the cushion or the plate made a bigger difference in metabolic cost.
That all said, carbon plate shoes do not work for everyone. Some runners find that their feet hurt in them or that they observe no real changes in running economy. Like any running shoe, the individual response is highly variable.
If you do plan on running a marathon in carbon plate shoes, ensure that the shoes will feel good for that long. I generally recommend marathoners test their race day shoes on one or two long runs of 18-22 miles before the race and one or two marathon pace workouts. However, you do not want to accumulate too many miles on a pair (unless you plan on buying a new pair for race day). 50-100 miles is an appropriate range for testing the shoes without too much breakdown before race day.
How do I Pick the Best Shoe for Marathon Running?
Whether you opt for a carbon plate or a traditional running shoe, you want a shoe that works for you. Popular shoes like the Nike Vaporfly do not work for everyone. Some runners may get an injury in a shoe that helps another person run a marathon PR.
Some factors to consider with a marathon running shoe:
- Stick to a heel-to-toe drop that works for you (within +/- 2-4mm). If you typically run in 4mm neutral shoes, you may not want to try a 12mm plated shoe. (Here’s a primer on what shoe terminology such as heel-toe drop mean.)
- Opt for adequate cushioning to support you over many miles.
- If you wear neutral shoes, stick to neutral – and vice versa if you usually run in stability shoes.
- A shoe should feel comfortable when you run. If you notice acute discomfort during the run or strange aches cropping up, the shoe may not work for you.

Almost every shoe brand has marathon running shoes and carbon plated shoes available. Amanda at RuntotheFinish provides an in-depth review of some of the most popular models of marathon running shoes on her website.
The information you have posted is very useful.
Thanks for the tips. My long run shoes are different than my short runs and different from the 5ks.
I only run in Topos because they have a low heel drop and wide toe box.
