Before putting on your new cleat-shoes, put on an extra pair of socks, this will help stretch the leather. Take them out and bend the edges to stretch them out.  Use a leather protractor to apply a coat on the base and then put them on again. After this, soak your legs (with the shoes still on) in warm water. After a few minutes, pull them off and keep them in a place to dry naturally. This will speed up the break-in process.
