blister on the back of my heels

I am so made bougth new sneakers this friday know ,i have blisters on my heals. How can i work out toss my old shoes away

Pad the spots that your feet rub with bandaids and gauze when you are wearing the new sneakers, till the blisters heal. When you're not wearing them, let them air out. By the time they are healed, your sneakers will be broken in!

What type of shoes did you buy? There's a way of cross tying the laces that helps prevent the back from rubbing. Go back to the store where you bought them and ask them to show you how to tie them. It uses the extra hole at the top to make a loop, then you cross the laces through the loop and it works.

I tried the bandage thing huts to bad. I bought new balance from marshall not sure if they would be able to help me.

Take them to a running store and ask them to show you.  Or when I get home tonight, I'll take a picture of mine and show you what I mean.

go to a new balance store. Tell them you bought them at a different new balance store, if they give you a problem. You may just have to wait it out till the blisters are healed. Try that stuff they sell at fitness/running places to prevent blisters. It's a cream type of stuff that reduces friction.
