Kolkata's climate doesn't often necessitate heavy snow gear, so finding women's snow boots might be a bit challenging. However, during the winter months, you might find a limited selection in larger footwear stores that cater to seasonal needs. Exploring malls or department stores that offer a range of footwear could be your best bet.Consider checking out online platforms that specialize in winter wear or larger e-commerce websites where you might find more options and varieties of snow boots suitable for women. Keep an eye on seasonal sales or promotions as they might feature winter footwear, including snow boots, even in places with milder winters like Kolkata.

Additionally, if there are any specialty outdoor gear stores in the city, they might occasionally carry a limited selection of snow boots during the colder months. It's worth giving them a call or visiting to see if they have what you're looking for.
