There are many places you can find a shoe designer or karigar (craftsman) for your online startup business in Delhi.
One option is to search online directories such as Justdial or Sulekha, which list businesses by category. You can also search Google for “shoe designer Delhi” or “karigar Delhi” and scan the results to find individual designers or craftspersons who may be able to help you.
Another option is to visit local markets or shopping districts such as Connaught Place, Khan Market, or South Extension, and speak to store owners or managers about designers or craftspersons they recommend.
There are also several professional associations or bodies that represent designers and craftspeople in Delhi, such as the Fashion Design Council of India (FDCI) or the India Design Council (IDC). You could get in touch with these organisations to see if they can recommend any designers or karigars who would be suitable for your needs.
Finally, you could also try contacting some of the bigger footwear brands or businesses based in Delhi, and asking if they can recommend any designers or karigars who work freelance or independently. Some brands or businesses you could approach include Bata, Catwalk, Metro, or VIP.
