IF your socks are looking a little bit tight around your ankles, it's usually because they have shrunk in the wash.
Your feet may also be swollen from the heat, but medics have warned that swelling could also be down to a silent killer.
Heart disease is one of the biggest causes of death in the UK – accounting for close to a quarter each year.
That's around one death every three minutes and it's estimated that over 7.6 million people are living with a heart or circulatory disease.
