Where to buy good quality boots in size UK 12/13 in Kochi?

Hi folks,

I'm looking to buy good quality boots in size UK 12 or 13 here in Kochi. The boots should ideally be waterproof or at least durable and comfortable enough to be used in wet or rainy conditions. Any recommendations for local stores or brands that stock large sizes and waterproof boots? Also, any tips on where to find reliable and affordable options will be really appreciated! Thanks in advance.
