Definitely get some new shoes and SPDs. There are a ton on "indoor" cycling shoe style out there with recessed cleats. I have a very old pair of nike "combis"....SPD with recessed cleat, very easy to walk in. It was really nice to have a spinning specific set of shoes - I could get dressed at home, drive to the gym (yes even in bike shoes - makes clutch work more interesting
), and take of my sweats and get right on the bike. I miss the spinning classes - they were a heck of a workout!
