I made a crowdsourced map for climbing stuff once. If there is a shoe shop, you can mark if they do repair climbing shoes as well: mapcomplete.org/climbing?z=13.…

Feel free to add your favourite repair shops too; it is all based (and saved into) #OpenStreetMap

Climbing gyms, clubs and spots

On this map you will find various climbing opportunities such as climbing gyms, bouldering halls and rocks in nature
