I purchased these shoes to be compatible with the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Shimano-PD-M540-SPD-Pedals/dp/B002LBNEVI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Shimano PD-M540 SPD Pedals</a>.  They are a superb combination.  These shoes are exceptionally comfortable and easily slip on.  The single ratcheting clip easily adjusts the snugness of the fit.  Eliminating the shoe laces means that an untied lace cannot be caught into the gear sprocket.  The Shimano pedals and bindings are very small and take training to learn how to use.  I loosened the bindings to their loosest setting for easiest entry and exit.  I practiced binding entry and exit while sitting on the bicycle when the bike was not moving.  Since the bindings will not release in an emergency, it is necessary to anticipate a stop.  I release my left binding well before a possible stop.  The shoes work well in this situation.  The waffle pattern on the bottom of the shoe allows peddling without locking in the binding allowing fast stops.  The rubber waffle pattern also works well in walking protecting the cleat somewhat but there still is some contact with the ground.  The cleats are designed to be replaced when they wear out.  Even at the loosest setting, the bindings hold well and will not release as the shoes are pulled upward to generate maximum power.  In conclusion I highly recommend this combination of shoes and peddles.
