About November time I bought some new black ankle boots, soft leather and the right size but my left ankle developed a lump and when you push it it sort of crunches. I have quite a high arched foot and my feet aren't particularly wide but some shoes/boots that cover the whole of my foot are uncomfortable. I was just wondering if anyone could help me! Thanks in advance.

Sorry about the bad quality but the lump is just above my heel.

If it is painful it could be the shoes have irritated the area and may have caused a infection. With that said either stop wearing the shoes and see if it goes away. You should apply ice to calm it down or just flat out go to the doctor.
