Never worn new old stock 1970s Platform Shoes, I believe these are Men's as women's platforms from the day were styled a little differently. No size marked on them,but anyone could wear these.... I would say a Men's size 8. or a womens 9.5. Wonderful for a groovy display in your soul train, funky town music room??? The inside shoe bed thing with the brand name is curling up on both. see last pic
