Yeah, get SPD biking shoes. Find ones meant for mountain biking, they usually have a recessed cleat that lets you walk in them like normal shoes. Also, be sure to have the cleat mounted as close towards your heel as possible, many people find that this eases any pain/numbness they experience when riding a recumbent.
And one more thing... we're not blind, so in your next post could you keep the text at a normal size? Thanks.
