Crocs Unisex-Adult On The Clock Clogs, Slip Resistant Shoes

Has anyone figured out how to buy replacement insoles or found aftermarket insoles that fit the wide shape of Crocs?

What is the fit style for this listing? Roomy, relaxed or standard?

Bought these a while ago- where can I buy replacement soles?

Usually wear 9w size shoes If you like this shoe size what should you order? And on a rainy day is waterproof well?
