There is very little choice for women with a slim calf in fact two in the Gabor range. The other style is Brooke I think with a flat wider heel like a riding boot. These were more my style though it is difficult to find out what they are made of. Comfortable and slightly lower heel than I usually wear so time will tell if my feet ache after wearing all day. Lovely style and due to sometimes wearing socks or thicker tights I went up a size. Note that they are not wide fitting across the width of your foot.
