Our shoes are true to size compared to most European brands. As a reference comparison: Take your existing sizes for sport shoe brands such as Brooks, On, Asics, Nike, Adidas, New Balance, Hoka One One and others. 

For these brands, go down a half or whole size, except for our Fire-Line models, which fit similar to the mentioned brands.

Still undecided? No problem - our 30-day return policy allows you to return or exchange them hassle free. Alternatively order a couple sizes and choose comfortably at home and return the shoes that do not fit.

Every GNL shoe is elaborately handmade in Europe. We only work with partners with whom we have full transparency, and we regularly visit the sites ourselves to ensure proper working conditions and production quality. Currently, our manufacturing takes place in a family-run shoe factory in the Bulgarian mountains. A small factory with a long history and importance within the village and community.


We also strive to never overproduce and try our best to match supply and demand in a sustainable way.

All our materials are purchased in Italy. We want to ensure short transport routes to reduce CO2 emissions, as well as ensure that all our materials meet the highest quality standards.


We want you to enjoy your GNL product for as long as possible. Through our re-sole program, you can help contribute to a waste-free society by extending the life of your shoes.

Healthy feet, healthy body

Regenerate while walking

Regular movement in GNL shoes reduces and prevents pain in the feet, back and joints in the long term. The intelligent sole also combats tired legs.

GNL stands for

Glide'n Lock

16 cushioning elements, which are 360° dynamic and let you glide into your stride, reduce potentially damaging micro-shocks in the body and then lock into position for a stable and energy-efficient push-off.

Swiss Design

Our design is minimalist. We do without frills so that every shoe is as light as possible. With an average weight of just 220g, each shoe is many times lighter than comparable sneakers.


Made in Europe

Quality and sustainability are a matter close to our hearts. We want you to wear your shoes with a clear conscience.



of your GNL shoes are worn out, they can be replaced. Resoling extends the life of your shoes.
