I recently purchased some stiletto heeled ankle boots by ‘Only Maker’ via Amazon. They were listed as UK12 (EU45 according to their conversion table!). I knew it was a risk - no reviews to suggest sizing was true - and when I took them from the box they looked tiny. I was surprised to find they fitted really well. Probably not suited to a wider foot. They have a set-back vertical heel which makes them tricky to walk in, but I really like the shape of the boot. The overall quality is not bad considering and feel very sturdy for such a thin heel.
I don’t mind a pointed toe, but I do prefer it when the toe mirrors the heel. So a stiletto heel looks best with a pointed toe, and a wider and more rounded heel looks best with a more rounded or almond shaped toe.
