A few notes on each:
Studded Lace Up: Beautiful shoe but very stiff and may run a bit small. They would likely need some breaking in but I love the small zipper on the back of the heel which would mean there is no need to lace them up every time you wear them.
Scalloped Flat: I love the look of these shoes and the price is unbeatable. They are super comfortable, but the color is not what I expected. They are the color of silly putty, not pink at all.
Suede Lace Up Flats: These are the most comfortable flats I've found. They are a stunning in person and I now have them in two different colors. Definitely the winners for me!
