If you are in the USA and need a Doctor but can't afford one/etc. i would recommend MyFreeDoctor
I personally enjoy and recommend Xero Shoes (bottom picture link) and VIVOBAREFOOT (top picture link) shoes, check them out some time! They offer great shoes that are wider that helps your feet to become their strongest while protecting from trash and sharp objects. 😃
If you are looking for sandals (not recommended), Xero Shoes has many options that are better for movement and activity that have a backstrap that secures the heel. Sandals (thongs/slides) damage your ability to walk normal by forcing you to drag your heels to keep them from falling off your feet. Over time this leads to people falling or injuries occurring because the legs are becoming stiffer and slower.
