I’ve bought several pair of Gypsy Jazz shoes. These are for my daughter in law’s birthday. I bought mine prior. I suggest staying to your true size. I am an 8-8.5 and buy GJ in 8. I can wear no peek socks, barefoot, & lately a medium weight winter sock. I do not notice much difference. The one pair I did buy for winter socks were 8.5 and I would not do that again as it’s not necessary as they are a bit large. I have friends who wear GJ and agree these are very comfortable. My go to shoe when I come home from work. I have worn the light black and light grey to work for casual Friday.
