window falls down and will not stay up

We have a vinyl replacement window (over 15 years old) where both the top and bottom sashes do not stay up in place (they drop down). Home Depot thinks they are called Red Top series 600 spiral balance pivot shoes that are a half inch thick, do agree? We are looking for replacement part(s).

Based on what you describe, it definitely sounds like the balances are the issue. The Series 600 is a good place to start. I suggest that you confirm that the outer tube diameter is 5/8" or 9/16". If it is, then that's definitely what we recommend.
Keep in mind that right now you have a cover in the jamb track that conceals most of the balance. This is not the tube I'm referring to. You should remove the balance from the window to get the most accurate measurement.
Alternatively, your balance may just need to be charged a few times. You can wind up spiral balances, sort of like a clock, to give them more tension. See the guide below for instructions how. 15-046, but you should carefully compare our measurements to yours to confirm. This would require you removing one of the shoes. See the two videos below on help removing these.
