I used to have flat feet; however, you can get some arches by doing certain exercises.
and running is on the balls of your feet (balls of your feet touches the ground first every step you make, not the heals)
Here are some exercises to get arches (I am 20 and I started getting arches within a couple weeks of doing this)
- focus on putting your weight on the side of your feet (the outside) when you walk and having your feet straight in line with your knee. (I used to walk like a duck before relizing this lol)..and back straight!
- stand against a wall with your back straight, feet right next to each other for like 30 seconds, then take a break, and then do it again (Do not over do it though)
- after you read this response, I want you to look down at your feet when you walk every now and then to make sure your feet are straight and not walking like a duck. Make sure your back is straight when walking and make sure your weight is on the side of your feet (outside end) and not the inside end.
After a while, your body will do this automatically and there ya go! =)
