So I've decided on a new frock for a party and I have a pair of knee high boots which I haven't worn for ages that would look great with them. I used to wear high heels a lot but not for a long time so I am really out of practice. Does anyone have any tips to make them at least a bit more bearable? There seems to be a lot of products on the market but not sure where to start. Boots are about 3 inches tall, knee high and leather (if that makes a difference.) TIA.
