Has adjustable back will fit 7.5-8 maybe 8.5. Never worn only tried on a few times. 5" heel 1.5" platform. An tad too high for me as ive been known to fall in flats when drinking. But I know a ton of girls can rock these so my loss your gain def. Adds a pop of color to any outfit. Excellent choice for the holidays. Sexy but simple enough and not a platform that huge that it would be classy and classic too
