A better way to choose running shoes.

Basically Hinge for your feet.

Try Eigen

Running shoes are engineered to the millimetre.You choose them because someone on TikTok said they’re “insane.”

The clever bit.

Why the 1080 fits you

Toe box
Wide. Your forefoot is 103.7 mm.
Cushioning
High. 35 km a week, mostly road.
Support
Neutral. The way you land doesn’t need correcting.

The research.

A few of the 200+ studies behind every match.

  1. The biomechanics of running

    Novacheck TF. Gait & Posture. 1998;7(1):77–95.

    How a running stride works, phase by phase. It’s how we read yours.

    DOI 10.1016/S0966-6362(97)00038-6

  2. Effects of step rate manipulation on joint mechanics during running

    Heiderscheit BC, Chumanov ES, Michalski MP, et al. Med Sci Sports Exerc. 2011;43(2):296–302.

    A small change in your step rate changes the load on your knees and hips.

    DOI 10.1249/MSS.0b013e3181ebedf4

  3. Running shoes and running injuries: mythbusting and a proposal for two new paradigms

    Nigg BM, Baltich J, Hoerzer S, Enders H. Br J Sports Med. 2015;49(20):1290–1294.

    The right shoe lets you run the way you already run. And it feels good.

    DOI 10.1136/bjsports-2015-095054

  4. Biomechanical Risk Factors Associated with Running-Related Injuries: A Systematic Review

    Ceyssens L, Vanelderen R, Barton C, et al. Sports Med. 2019;49(7):1095–1115.

    What actually predicts running injuries. And what doesn’t.

    DOI 10.1007/s40279-019-01110-z

Eigen helps you choose shoes. It isn’t medical advice. If something hurts, see a professional.

Free. And independent.

How Eigen is free, and how it stays honest.

  1. Funded by a grant.

    Eigen is backed by a grant from ETH Juniors. That’s why it’s free. No subscription, no catch.

  2. How we might make money later.

    People ask. Fair question. Down the line, we may earn a commission when you buy shoes through Eigen. If that happens, we’ll tell you. Right here.

  3. What will never change.

    Commissions will never touch your ranking. The algorithm doesn’t know who pays, and it never will. Your match is your match.

  4. And maybe a better price.

    If we do work with shops, we want it to get you a better deal on the pair you were going to buy anyway.

Loyal to feet, not brands.
