<human>: Can you condense the text into a few key points?

Since leaving high school back in 2012, I always kept my old running shoes. From Senior year in 2011 up until summer of 2014, I'd used the same shoes for 3 years. I didn't run as much in college, so I didn't think it'd be worth spending another $100 on new shoes.

Well I started running a lot more in 2014. Not too much, but maybe 20-30 mile weeks. It was enough to start making my feet hurt. I noticed that my right foot hurt a lot more, and it was because the sole was so destroyed on the toe side that it actually sunk down. 

Eventually, I bought new shoes in fall of 2014, but by that point I think the damage was done. Even when I walk now, I feel a lot more pressure on my right big toe compared to the rest of the foot. Like when I walk with left foot it feels normal, with the weight distributed somewhat evenly. But it's completely off for me on my right foot. When I run for more than a few miles now, my right foot will start to hurt, and I think running for that long with my foot has gotten my lower back to hurt more as well.

Is there anything I can do to remedy this? I was thinking about orthopedics but those are usually more for problems with the arch.
<bot>: Fucked up my foot with 3 year old running shoes. Foot problems continued even with new shoes. Is this permanent? Can I fix it? How? Help pls.
