BMW Mountain Bike Enduro Owner's Manual page 88

Only use clipless pedals allowing you to engage and disengage
smoothly (a). A defective pedal or a badly worn cleat can make
the shoe disengage from the pedal. Or unclipping the shoe
from the pedal is sometimes very difficult or even impossible. In
both cases, there is the danger of an accident!
Inform yourself at a bicycle specialist shop of your trust about
the various models of cycling shoes available. Cycling shoes
come in various styles for specific uses.
Some mountain bike pedals, also referred to as platform ped-
als, are designed for maximum grip of the shoes when dirtbik-
ing and freeriding (b). For this reason they have sharp edges
and/or bolted pins. As they enhance the risk of injuries during
riding, you should wear protective clothing, e.g. knee and shin
guards.
