Velotoze are an Absolute pita to get on.. worst purchase in a long time. But Very effective and very aero. Got 2 trips out of them
Apparently the proper technique is to roll anklet style up the ankle and unravel them over the shoe.. at which point they tear and you put them in bin.
sealskinz last approx 30-40mins in proper rain.
i quite like the look of velotoze but haven't actually tried them
only thing that works 100% is wellies + waterproof trousers.
