With SPD pedals the amount of float is determined by the type of cleat, of which there are a few different kinds.

You had the Shimano SH-56 cleat on before, which is a multi-release cleat with float.

What you have on there now is the SH-50 which is a single release no float cleat.

You need to purchase either the SH-56 multi-release or the SH-51 lateral release cleat to get float.
