i personally would not wear them as they look like they have no spine on the back to stop you from snapping your ankle and yes i have had bikes all my life and had a off on my r1 and beleive me your foot is the first bit to dig into the ground ...........and you could have bought a brand new pair of boots for £100 with airflow and spine down the back as i was looking at some the weekend.........

like plenty have said on here you get for what you pay for......
