Ski boots sole were reversed engineering after they broke off.
Printen in 80% infill ABS, and lasted for about 2 weeks before i had to replace them.

Although the ski shoe was quite old, perhaps some of you might have the same problem?

Perhaps printed in full plastic, it would be better, and long lasting, but i printed it with this rigid red ABS: https://www.goedkope3dfilamenten.nl/premium-abs-brandweerrood/
