Ripping on heel
Overall, extremely comfortable. However the heels have started to rip, and there is a spot on the right upper ripping as well.

Very nice to work with and buy from, both from a seller and consumer standpoint.

Wonderful and straightforward ordering experience that has resulted in the most amazing pair of shoes.

The shoes fit very well, and i love that they can be recycled! This is so hard to do with regular modern shoes. They are a bit expensive, but since i usually have problems with finding shoes that actually fit me because my foot shape is a little irregular, these were woth every penny because they actually just fit. They definetly are a conversation starter, but i dont mind that. Overall, very well done, just make more different types of shoes please, i dont know if it would be possible to make hiking boots like this but if it is i would definetly get those too!

Custom measurement of each foot, as I knew they were different, was important to see how that felt when wearing properly fitted shoes.

It was a great purchasing experience and I've immediately put on my new space shoes!

Love the personalized note in the box and on the label

Mir hat die Kommunikation gefehlt. Ich musste stets nachfragen was mit meiner Bestellung ist, habe nie Mails zum Fortschritt erhalten. Das ist ein wenig nervig, gerade wenn man bedenkt, dass man modern und fortschrittlich sein möchte.
