I use a pair of Look Keo pedals with the red cleats provided in the pack and find that there's a lot of float and find it difficult to uncleat. Is this due to the float or due to my shoes being too wide or my feet and socks being wet or all of the above? I'm wondering if getting the grey or black fixed cleats will result in easier release. It makes me nervous not being able to uncleat as easily as when I used Shimano Ultegra pedals. Should I try the grey or black cleats or revert to my Ultegra pedals? I fell on my side (thankfully on the beach) today during the transition from bike to run as I couldn't get my foot out, and my first triathlon is next weekend.
