DOnt settle for getting used to it.Your feet tie into knee,neck,back and other problems.As you age you will start to feel the aftermath of doing this to your feet.Im 33 and did sports,skated and everything else in flat shoes and it turns out since my late 20s my feet are always killing me.I needed a higher arch and more cushioning.So go buy a good jogging shoe or dr approved shoe and take out the crappy insole and instal a nice cushiony one.Take a day when you think the stores wont be crowded and spend a couple hours trying diferent ones on.If you know of a running store then check them out,they know all the tips and can usualy tell if you over or underpronate.They make shoes for either one.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,Take my word for it,feet are very importand and they will remember how you treated them down the line.Good luck.The 100 buck range of the sacconys are very cushy.I know thats not how to spell that brand but Im not sure how to,lol.Asic high end stuff is good too.
