caption_attribution_description: English: A Shimano MT31 cycling shoe with a SH56 SPD (Shimano Pedaling Dynamics) cleat attached. The MT31 is an entry-level shoe, with a versatile tread designed for walking on a variety of surfaces.
context_page_description: Shimano Pedaling Dynamics, commonly called SPD, is a design of clipless bicycle pedals and associated cleats first released by Shimano in 1990.
  Shimano makes a number of different SPD cleats, and not all cleats are compatible with all pedals, especially between "road" and "mountain" SPD product lines. Among otherwise-compatible cleats, there is an important distinction between black "single release" cleats and silver "multi release" cleats. The former can only be released from the pedal by twisting the heel outwards, while the latter can also be released by a sharp pull upwards and are therefore easier to use for novices.
  There is a small adjustment screw on the pedal that can be used to alter the resistance required to release the cleat from the pedal, so beginners can have it 'soft' and easy to get out, and then tighten it up as they progress.
