1970´s-80´s Black Knee-High Boots Ostrich Leather size 8/8.5 US Women´s

Vintage 1970´s-80´s Tall Boots. Maker/Brand unknown, size worn off. Please read full description for sizing/fit. These are very high quality. Black Ostrich Leather. Leather insoles and lining. Pull on. Classic "Ostrich" dot textured leather below the ankle and a smoother but still lightly textured leather on the shaft. Almond shaped toe. Low Heel. In Excellent condition with light wear, only really noted at the soles which still look to have plenty of wear before having re-soled. I´m guessing these to fit a women´s 8-8.5. I wear a 9-9.5 but can get my foot into an 8.5 wearing a thin sock. Please compare measurements to a similar style in your closet and message for any help/tips.
