Barefoot Beginner

I am just starting to get into the barefoot world. I have pretty wide feet and issues with shoes that are too narrow for my toes. I am looking into these Groundies Starlite. It looks like from past discussions these used to be a regular fit, but now they're listed as barefoot. Would these be a good beginner shoe? And which size I should go for? I am usually a 7.5. Should I size up to an 8 or down to a 7?
