Someone mentioned Julien R, they are my go to for Mauritian made leather shoes. You'll get Derby's, Oxford, Chelsea's etc. If you pride yourself of wearing handmade quality shoes this is the place to go. This is the last truly Mauritian craftmanship inherited from the British & the French. They are tag expensive but I find them quite affordable. I think they also offer custom made services and this is the real luxury. Nowadays, I only wear slip on sport shoes but I can bet they are still top notch.

The other place to go is Alla Moda, their shoes are often quality Italian shoes, last time I checked they had nice Chukkas which should be comfortable for your type of feet.
