I will start by saying I'm not a Toms show person at all. I don't own any other Toms product at all. But these are great!
I generally wear an 8, and the 8 Black suede Toms bootie was no different. Perfect fit. For reference I do usually end up choosing a 7.5 for sandals and open toe dress shoes. The round toe is perfect. It has height but not to the point it's uncomfortable or you start to worry about walking one drink in.
Although I wouldn't say I have a wide foot, occasionally dress boots seem to be too tight and uncomfortable for me. Especially the type that seem to have a molded pump-heel type base in them - which these do not have. They are a real boot! The boot style is amazingly comfortable. The footbed has mild arch support in them which is better than most which have zero it seems. I could use more arch support but that's normal for me in any shoe outside of my Danskos. They are a normal width for a average person. If you're a pencil you will have pencil width feet.. I love these so much I got on here to look for an additional color option to buy.
