Five Ten Freerider Pro

Most mountain bikers, regardless of skill level, should probably be riding flat pedals rather than clipped pedals. If you are, purpose made flat pedal mountain bike shoes are a huge upgrade over regular sneakers. And the Freerider Pro from FiveTen are probably the best you can buy. They are super comfortable, have a nice sticky bottom to help you connect with the pedals, and have some water resistance. I've only owned one pair of these and they're the ones I bought 3 years ago and I'm fairly sure they've got at least 3 more years of life left. I've worn them in everything from 100 degree sunny days in Texas to 40 degrees and raining in the PNW and have never felt like I needed a different shoe. If these ever do wear out, I'm buying another pair without hesitation.
