What is RunRepeat?

RunRepeat is a footwear review site that buys shoes with its own money, cuts them in half, and lab-tests them to produce in-depth reviews. It's useful if you want independent, measurement-backed information before buying running, hiking, or other athletic shoes, rather than marketing copy or first-impression reviews.

What RunRepeat covers

The site organizes its content around shoe categories and review types:

The homepage states that more than 1,000 shoes have been reviewed and cut in half, with 19 shoes currently being tested and 21 bought and waiting to be tested.

How the testing process works

RunRepeat describes a three-step process:

1. Buy and cut — Shoes are purchased with the site's own money, cut in half, and assessed across more than 30 parameters.
2. Wear test — Shoes are worn in their appropriate settings.
3. Standardized comparison — Tests are standardized so results are comparable across shoes.

The cutting step is central to how the site measures things like midsole softness, which can't be judged reliably from the outside.

Guides explain the "why"

Beyond individual reviews, RunRepeat publishes in-depth guides on shoe technology and performance factors. Examples listed on the site include:

• The ultimate guide to running shoe foams
• What makes a running shoe faster?
• Behind the price tag of running shoes
• Shock absorption in running shoes
• Energy return in running shoes explained
• Why cutting running shoes in half is key to measuring midsole softness
• The role of heel counters in running shoes
• A runner's guide to choosing the right toebox
• The definitive guide to running shoe breathability
• All you need to know about rockered running shoes

These are useful if you want to understand what a spec or design feature actually does before comparing specific models.

What you'll find on the review pages

Reviews are dated and cover named models. Recent examples include the PUMA Deviate Pure Nitro, Saucony Triumph 24, HOKA Arahi 9, and Brooks Revel Max. Popular reviews include the Brooks Adrenaline GTS 25, ASICS Superblast 3, HOKA Clifton 11, and Nike Vomero Premium.

Who it's for

• Shoe buyers comparing models who want lab data alongside wear-test impressions.
• Runners, hikers, and other athletes who want category-specific reviews and buying guides.
• Anyone curious about shoe tech who wants plain explanations of foams, energy return, or breathability.

Things to know before using it

• The site also runs partnerships, including footwear testing and prototype testing, retailer data access via API, and affiliate content. Reviews are presented as independently purchased and tested, but it's worth knowing these business relationships exist.
• Content is available in English and Spanish.
• RunRepeat is a review and information site, not a retailer — it links out rather than selling shoes directly.
