I used to wake up every morning with terrible pain in the tendons on the backs of my heels, to the point that, every step I took was painful. It would take a good 5-10mins every day before I could walk properly. I lived in flip-flops.
That's why I started to read up about shoes, their impacts on our health, and how Lollapalooza became a new ladies' shoe brand.
If you relate, you should invest in shoes that support your feet and back too.
