“How can I treat cramps while running?”

There can be several reasons for developing cramps:

1) Running shoes
2) Shoe inserts - old or do you need them - goes with looking at the shoes
3) Running surface - avoid concrete - try track of trails
4) Level of hydration - including any medications or medical conditions.

All of these may need to be evaluated to determine the source of your cramps.

Cramping is usually due to a combination of two different factors. One is dehydration but not with only water but also electrolytes. If you are considered a super sweater, meaning that you have rings of sweat around your clothes after you run, then you have to hydrate even more than regular people. The other reason is because of low magnesium. Be sure to properly hydrate and alternate something with electrolytes like Gatorade or Powerade. And then also take a liposomal form of magnesium that Has a better absorption rate.Proper stretching of the calfs, and plantar fasciitis is also very important. Changing your shoes every 500 miles as well.

Stretching, strengthening, hydration, and occasionally there is an electrolyte imbalance.

Use Liquid IV. Your best source for natural hydration and electrolytes.

Cramps can be caused by many factors: dehydration (not drinking plenty of water), poor diet (not a balanced diet), poor quality/old (worn out) shoes, lack of warm stretching/flexibility program, poor circulation, etc. You may want to discuss with your primary care provider for an evaluation and possibly laboratory testing.

Most likely shoes and arch supports are the problem. This is dependent on how Your foot is shaped, thus I am at some disadvantage here.
That said, I would take Your running shoes and go to a legitimate running store. In San Antonio, I prefer Fleetfeet.
Other less likely less causes would be back / nerve issues, medical conditions or exercise induced compartment syndrome where muscles are not receiving enough blood flow due to swelling.
