I have to thank my sweetie for these. He got them for me off eBay. The auction said 40's 50's, but I think they are definitely 50's. If anyone knows better please correct me. I am so excited to go swinging in these. While I can lindy pretty well in my Cole Haan's (as Jenny can atest to), I wouldn't mind a smaller heel. My Cole Haan's sport a 5 inch heel. Yes, I dance in that. So going down to a 3 1/2 heel will be a blessing for my doggies. I can't wait to wear them out. Possibly on the 25th, when I wear my new black dress!! Yay!
