Vintage 70s Neutral Open Toe Ankle Strap Sandals - Summer Shoes by Naturalizer
No materials indicated - I would guess man made parts. Have a somewhat cushioned feel.
Size 7 N - Please check measurements to be certain of fit. I wear size 6 and these fit but a bit loosely in heel, feel like a 7.
Insole length: 9. 5". The inner heel measures just under 2" across. The widest part of ball of foot is 2. 5". Outside vamp is 4" at widest. Heel is approx 3" tall. Please ask if need any other measurement.
Good condition - Please note minor wear in photos.
