Boots and tennis shoes

purchased both at thrift store. could very well be knock offs- unsure. boots are size USA 6. however I wear women's 8 and they fit perfect. the tennis shoes say US 7y. I wear size women's 8 and they fit perfect. well used. selling for less than what I paid at thrift store. let me know if you have any questions. I listed shoes under women's size 8 but please note the tag say different sizes as just mentioned.
