Shimano SH-M087 MTB Shoe: The Shimano SH-MO87 Mountain Bike Cycling Shoe are the even better update for the already super popular MO86. What you'll find this year is an even roomier toe box, this along with a more durable and lighter weight rubber sole that's also grippier than last years offering. Perfect for Mountain Bikers who want more than something basic, while not breaking the bank at the same time.
