These are so cute, true to color, and comfortable.  I LOVE Puma flats they are always so comfortable.  I have problems with most flats because they rub my Achilles tendon raw, but these never do, which is why I own so many of them.  I will say that I am a pretty solid size 8, but I absolutely need a 7.5 in Puma flats (ALL of them).  They also tend to be slightly wider than normal so there's extra room there too.
