J Crew Leather Ballet Flats Light Blue with Silver Cap Round Toe Fits Like Size 5 Great Pre Owned Condition with wear noted to the silver strip on the right heel & a small mark on the left toe (tried to capture both in pics). ***5.5 is the size marked on the shoe. I can normally wear size 5.5 and these are tight on me. Actual fit is more like a 5 but please compare measurements ( see pic).
