Waterproofing Golf Shoes | Golf Monthly
Q: What's the point of water-resistant golf shoes in Britain?
A: There isn't one!
Q: On how many occasions would NON water-proof golf shoes be of use in Britain?
A: Err....you got me!!
Conclusion: Slipper-like comfort in a golf shoe is over-rated if you cant wear it when the weather is changeable.
Unless you have (or want) webbed feet!
To the OP: You could try Nik Wax Shoe Waterproofer. It comes in a spray can and saves many shoes for an extra season or two. But it wont help if they already leak or are made of synthetic materials. HTH
Edit: Shucks! Beaten to it!
