Had a trip from Melbourne to Sydney wearing the Grand Prix water proof boots. Bought after reading this thread: https://netrider.net.au/forums/viewtopic.php?p=630219#630219 Must say I am quite happy I decided to buy and wear these boots up for the trip. They kept my toes insulated from the cold and wind chill. On my normal trips to and from work, my toes would just about be frozen solid. This from a 30 minute ride in my Sidi vertigo boots. I was riding for almost 6hrs in the cold and my toes remained warm enough that it didn't distract me from concentrating on the rest of the boring ride. Comfortable enough to walk around in aswell I forgot to bring a pair of casual shoes with me.
