Sehr bequemer Schuh. Einzig die Stabilität Innenrist fehlt mir.


GNL Footwear

Lieber Fabian, vielen Dank für deine Bewertung. Wenn du zu Überpronation neigst, empfehlen wir dir, die Standard-Einlagen durch mehr stützende Einlagen zu ersetzen. Wenn du einmal in der Nähe unseres Showrooms in Zürich Wollishofen bist, kannst du gerne vorbeikommen, damit wir dir eine kostenlose Beratung anbieten und deinen Gang analysieren können. Manchmal können wir dir auch Tipps geben, wie du das Fussgewölbe stärken kannst, um Überpronation und Plattfüsse auf natürliche Weise mit GNL zu verbessern. Wir freuen uns auf deine Rückmeldung! Liebe Grüsse, dein GNL-Team

Very satisfied! These are the best shoes I've ever owned and I walk a lot! The feeling of the cushioning is indescribable. It really does feel like your floating. I also love the elastic laces, which make the shoes super easy to slip on and off. They also look great!

Matt S.

Most comfortable shoes ever

Best walking sensation I've ever felt. I'm a GNL customer for life! Also great quality leather.

Thomas B.

Very satisfied customer living in Hong Kong

I have to disagree with the review from Mr. Peter. I have had these shoes now (not this model but in a different color) for 2 years and love the elastic laces! Lining is still perfectly in tact. I'm buying these in grey now and can't wait until they arrive!

Peter S.

Actually a disappointment

Bought the shoe on 03.02.21 and was delighted by its comfort. However less so by its design which appeas flawed to me since the elastic laces don't allow for 1) a tight fit and force the owner to 2) overly stress the inner lining made of textile when putting the shoe on as the elastice laces don't allow for a wide opening. As a consequence the inner lining got torn after not even 3 months, which is really disappoining considering the price of the shoe. I'm writing my review in the hope that improvements ('normal' shoe laces/more robust inner lining) may find their way into this shoes design as otherwise it makes for a really fantastic walk.

GNL Footwear

Dear Peter, thanks a lot for your review! We are super happy to hear that your walking experience with GNL shoes is fantastic and that you are enjoying the unique comfort sensation our proprietary shoe sole technology has to offer! In regards to your experience with the shoe laces, we are really sorry to hear this. And it should definitely not happen, as our shoes are designed only with the highest quality materials and rigorously tested to be able to perfectly adapt the laces as needed to easily slip them on and off. If the laces are adjusted correctly and there is no faultiness with the product, then you should not be experiencing any difficulty. We do have a one year warranty, so please contact us at and we will be very happy to look into it further! Thanks and kind regards, Eric Braunschweiler CEO & Co-Founder

healthy feet, healthy body
Regenerate while walking

Regular movement in GNL shoes reduces and prevents pain in the feet, back, and joints. Besides, the intelligent sole works against tired legs.

GNL stands for
Glide'n Lock

16 cushioning elements that are 360° dynamic and let you glide into your step, reducing potentially harmful micro shocks in the body, then lock into position to enable a stable and energy efficient push-off.

Swiss design

Our design is minimalist. We don't use unnecessary frills, in order to keep our shoes as light as possible. With an average of only 220g, GNL shoes are some of the lightest shoes on the market.

Made in Europe

Quality and Sustainability are matters of the heart for us. We want you to wear your shoes with a clear conscience.



Get the most out of your GNLs and restore cushioning and profile for an as-good-as-new feeling.
