No! Every pair of custom shoes are made with care and years of experience to be fully wearable. You can enjoy them as much as you wish.
With that said, they are still an art piece and are not immune to expected wear and tear. Treating your shoes with care is a must in order to keep them in pristine condition.
A good rule of thumb is: “Whatever you wouldn’t do to your most expensive pair of shoes, don’t do to these.”
