The Sunday Times recomends

Granger's new G-Max Universal Footwear Proofer was  presented yesterday by The Sunday Times in their 'Good Gear' section. This spray-on waterproofer is suitable for all types of outdoor footwear and is so easy to apply; just clean with Granger's G-Max Footwear Cleaner and while still damp spray all over with G-Max Universal Footwear Proofer. Leave to dry at room temperature and that's it!
