Mountian bike shoes are specialised shoes designed to be much more hard wearing than road cycling shoes are. MTB shoes are supposed to take some hammer and be resistant to all weathers, given the nature of mountain biking.
A good pair of mountain bike shoes will have all weather protecting and often a rough sole to help you gain tracion on corners or when climbing if you come off the bike. Like road shoes they usually have a quick release system for easy tightening and loosening - ideal for getting them off when caked in mud.
At Cycle Division we have a range of mountain bike shoes from top brands including Scott, so you can be confident of the quality of your purchase. Scott cycling shoes are used by professionals around the world in both road, mountain bike and cyclocross disciplines.
