I've been interested in the idea of getting a cage or special shoes with pedals, and was just wondering on some opinions from other commuters.

I don't want to have to change shoes, so maybe the cage may be a better option, but what's the difference performance wise? And are there any shoes that also double as general shoes so I wouldn't have to worry about walking in them?

My general commute is about 13 miles each way (26 miles) mon-thurs to campus, then a bunch of small rides (store, friend's house, work, etc.) throughout the week. I generally end up at between 120-150 miles a week. Specifically for the longer rides (like school), would be nice to have a bit of an upgrade.

Any recommendations? I have a lot of amazon credit, so things purchasable there would be preferred
