So what, specifically, should you look for? The prerequisites are few but important. The sole should be thick to dampen vibration, resilient to resist hard or sharp objects, and should feature a grippy tread pattern to provide traction on irregular or slick road surfaces. The boot's outer construction should be rugged enough to protect your feet and ankles from the external assaults of the road. Look for flexible, internal heel and toe cups. Extra shin protection also rates high on the desired-features list, but you'll find this bonus mainly on sport or touring boots. Boots should also securely attach to your foot to prevent slippage in the event of a crash. That means tailored boots with zippers or laces are best for staying on your feet in the event of a get-off. While certainly popular with cruiser riders, slip-on engineer-style boots are more likely to come off before they've finished doing their job.
