I have skinny calves too. I’ve two pair of stiletto boots from Italian heels - both are their Tina model, one (black) with 10cm heels and the other (chocolate brown) with 12cm heels. They fit very nicely around my calves. They were not cheap, but they are well made, real leather - I’d much rather have only a couple of pairs and have them fit beautifully.
I’ve a pair of very beautiful, luxurious black suede OTK boots custom made by Jean Gaborit that fit absolutely perfectly, and their sturdy, slender 9cm heels are extremely walkable. But you do pay for that …
