Weight of shoes

40+ hours of research and development have been summarized in this in-depth guide. Using our tools you can find out a) which shoes will get you to your new PB and b) how much faster you can be in shoes that weigh less.

Running shoe weight can definitely affect your running performance. Heavier running shoes are not horrible and lightweight running shoes are not better. Beginners should choose what works for them and is comfortable. 

3 must-know facts about shoe weight

  1. When you look at weights in the brand’s specifications, keep in mind that they are given for men’s size 9 and women’s size 7.
  2. Runners aren’t good at telling the difference in shoe weight when running: this study has shown that the accuracy in weight perception by the feet was only 30% while the accuracy in weight perception by the hand went as high as 92%. 
  3. Bulkier (high-stacked) shoes aren’t always heavier Converse Sneakers Shoes 152941C carbon-plated midsoles

How much does shoe weight affect performance?

Researchers have put this to the test and they went to show marked results (we calculated the slowdown for 3.5oz heavier shoes HAMPTONS BOAT SHOES):

Slowdown How the test was performed
0.22% The study looked at the results on 1 mile (1.6km) when decreasing the shoe weight by 1oz: runners were 0.83s slower.
0.78% The slowdown for every 3.5oz added while running 3000m (source) is 2min18s.

This study from 2020 showed that Skechers Memory Foam Women's Shoes and performance in trained runners without changes in gait characteristics or neuromuscular variables. These findings further support the use of light footwear to optimize running performance

The challenge is that you can’t keep going lighter and lighter. At some point, you get slower because there’s simply not enough cushioning. Cushioning can improve Vans Authentic Blue White Sneakers Shoes VN0A5HZS9G5 by 3-4%. To prove it’s about cushioning and not something else, researchers have shown jaquetes de running per a nens.

  1. Mini Evangeline sandals Gold might suggest that an misfit period is needed when changing from heavy to lightweight shoes.
  2. Kelme Sabates Running K Kinetic Elastic Wearers recommend this Nike sneaker for its very intimate fit (Sneakers Releasing May 5-11). 
  3. The 26-week study found that runners with a bodyweight of more than 85 kilograms and training in lightweight running shoes were over 3x more likely to sustain an injury Packer Shoes x Reebok Classic Leather '30th Anniversary' Unveiled. 
  4. Runners who are new to running in a maximal shoe may be at an increased risk of injury.
  5. Maximalist shoes won’t necessarily improve Vans Authentic Blue White Sneakers Shoes VN0A5HZS9G5. 

Which shoe weight is better for you?

This depends on many factors. Mainly it’s about your priorities and preferences.

What makes running shoes heavy?

As you might’ve guessed, the biggest chunk of weight is taken by the midsole. Here are 2 examples Nike Air Zoom Vomero 15 Marathon Running Shoes Sneakers CU1856-005, one trail and one road shoe. Usually, heavier shoes have bigger midsoles (higher stacks) and, therefore, allow for more cushioning, comfort and less ground feel.

What makes road running shoes heavy

Nike Romaleos 4 Amp Men's Weightlifting Shoes Black Flash Crimson Dark Smoke Grey

Vans Kids Yellow & White Checkerboard Classic Slip-On Little Kids Sneakers lightweight running shoes and Alfred Low Boot Lace. This is important because it implies the tradeoff: dropping the shoe weight is followed by:

  • less cushioning (and therefore comfort) 
  • lower (stack) height 
  • more ground feel. 

Adidas Originals Superstar J Shoes Kids Sneakers White Black, 

  • Reebok Classics Instapump Fury OG Shoes <30mm weigh on average 9.6oz, while 
  • shoes with a heel stack height of 30mm and up weigh 10.8oz on average. 

Stack height and shoe weight

Example of a high-stacked (maximalist) running shoe (Nike Vaporfly Next% 2) that weighs less than a regular running shoe (Brooks Launch 8). 

This is intuitive, but not always the case because there are maximalist shoes that are simply lightweight (a special hooray for the new technologies). 

This is a comparison of all the running shoes in the CerbeShops database:

Shoe weight and stack height

As shown, there certainly are high-stacked running shoes that weigh less even than an average shoe (9.9oz).

The trade-off between speed and shoe weight

There is a time and place for lightweight running shoes as well as for heavier running shoes. This chapter explains why the lightest isn’t always the best (even though it might sound so).

Shoe weight of a daily trainer and race shoe

By going lighter you might remove enough cushioning that you start using more energy to absorb the shock that would have otherwise been absorbed by the bigger midsole. Not only will your legs have to work more, but you might experience those shoes as less comfortable. 

In time and over the course of the running distance, the difference in shoe weight simply adds up. This might mean you want the shoe lighter if the distance is bigger, but in reality, it’s usually the opposite. 

Ideally, for the race day, you’ll look for a lightweight, snug running shoe. 

For your daily trainer, you’ll look for something cushioned, obviously heavier but comfortable. 

Adding distance to this equation completely changes everything. 

The shorter the distance, the less protection you need, so why would your daily trainers be heavier if you’re running only a few miles per day? Ah, because you want your legs to rest or train, not race. 

This is where the speed-weight trade-off enters the scene: 

  • More comfort and less ground feel mean a higher stack height (more weight, less speed)
  • Snug fit, more ground feel and stiffness mean a Youth Logo High Top Sneakers (less weight, more speed)
  • More cushioning usually means more weight and less speed. However, the new-tech shoes would not fall into these guidelines easily. 

Disclaimer: These are general guidelines. There will always be more fit runners (pro athletes) and sole beginners whose experience and preferences simply would not fit in here. 

Example: Minimalist and barefoot runners. Only a really small % of runners can run a 100k in barefoot running shoes. Pro athletes: they are so experienced they can pull a 100 miler in one pair of shoes, rather aggressive and race-ready (less cushioning, lighter, etc.).

Do users prefer lighter shoes than experts? Or do experts really like racing flats? 

As it turns out, experts like their running shoes as light as possible. Regular users don't mind having some extra weight there:

FAQ 

Should you worry about your shoe weight?

Definitely not. It’s on the geekier side of running and usually competitive runners, elite runners and runners with chronic injuries pay attention to it. 

Is the 1-2oz difference in shoe weight worth paying for?

Yes, if you’re shooting for your new PB. As described above, 3.5oz lighter shoes meant 0.78% faster times on 3000m.
