I tested Daytona's Travel Star Pro GTX boots (costing around £459) for six months, covering 8000 miles.
These boots are insanely expensive but they’ve been near flawless. I’ve put a good 8000 miles on these boots through the depths of winter and (as well as still looking nearly new) they’ve never let a single drop in, nor showed any sign of doing so. With a thick pair of socks I was comfortable right down to near zero.
These are the Pro models, which come with more protection than the standard Travel Star but, even though they’re CE-approved, they still feel a bit lacking.
The sole can be a bit slippy on rubber pegs in the wet too but I’m nitpicking. If you’ve got the cash, these should be near the top of your list.
