I have TERRIBLE posture, have worn the same workout shoes for the past 3 or 4 years, and NEVER stretch. Like, I stretch my hammies and quads for about 10 seconds each before starting my run. I haven't replaced my shoes because they don't seem to have any wear but perhaps I could look into a more comfortable brand. If it's my back- I'm ****ed..
I was having issues until I made my feet into a V during squats and it went away.
