From what you're telling me it could be a fungal infection and should try over-the-counter agents, and if no improvement seek a dermatologist or a podiatrist
It could be as simple as a proper shoe sizing problem, or it could be some type of dermatitis. Get properly shoe sized at a shoe store (while standing - NOT seated). Otherwise consult a Board Certified Podiatric Surgeon to be sure there is not a medical issue in your case.
Can try mole skin to the back of the shoes. But when looking at a shoe when you are buying make sure the back you cannot squeeze it closed easily, if you can there is no support there and this can be a cause of the blisters.
You may have biomechanical problems with gait and should seek a podiatrist.
Blisters are associated with a condition call athlete's feet, or Tinea Pedis. Please see your local podiatrist for an evaluation.
Could be athlete's feet or infection. Should have it evaluated
Haglunds deformity can result in blisters. This can be surgically repaired.

The blisters may not be caused by your shoes; it could be a fungal issue exacerbated by being in shoes and sweating. You should see a foot doctor for evaluation.
There are many reasons why you keep on getting blisters on the back of the feet. The blisters can be secondary to friction due to an underlying prominent bone or due to an underlying skin condition, such as athlete's foot. Please see a podiatrist for further evaluation.
Your blister can be due to a persistent area of increased pressure on a localized location on your foot. Could be from the way you walk or biomechanics. Switching shoes will not always reduce the pressure or friction in that spot.
It is a matter of shoe fit..it has become more difficult to find shoes with wide toe box and narrow heel. Buy for the front but ask for a half sole which should make the heel fit better
If your feet perspire too much, the excess moisture will lead to blisters, even in other shoes. Keep the feet as dry as you can, using a topical clear gel anti-perspirant is one way to try.
If your shoes rub, you will continue to get blisters. I would recommend an evaluation by a podiatrist to see if you have a possible bone spur on the back of the heel, which can be contributing to this problem
The problem may be the wrong size or need of support in the shoes. Sometimes an orthotic is best.
Getting blisters on the back of your feet is usually due to the shoes rubbing against the back of your feet where there may or may not be a bone spur. This should be evaluated by a sports podiatrist who can make a proper diagnosis and determine message to relieve your blister formation. It may be as simple as changing the shoes you wear or possibly making some kind of an insert to go into your shoes.
Blisters are caused by friction and moisture. New shoes are usually harder than worn in shoes which will cause increased friction.
Blisters are mechanical in nature. You most likely have a biomechanical issue where your foot may not be functioning optimally. Sometimes Orthotics can help change and improve the mechanics of your feet and resolve theses issues. You should get checked by a local Podiatrist in your area to see if he/she can help you correct the issue
Blisters are caused by friction. Either your heels are too narrow and rub, or the heel cup of your shoes are too wide, or both. Simple blisters are a mechanical problem. The easiest way to fix this is to make your shoes narrower because it's difficult to make your heels wider. I would suggest making your shoes narrower in the heel by lining the heels all the way around the heel cup with moleskin. Be careful not to have any ridges in the moleskin. A cobbler may do this the best. This procedure is better than applying moleskin to your heels.

Most likely the type of heel counter on your shoes along with the material and sizing.
Most likely your heels are slipping up and down. Need to snug up the fit around your heels. Either tape a 1/4 inch piece of felt on the tongue of your shoe or wear heavier socks and tighten your laces.
It could be an issue with how the shoes fit and/or could be a structure that is interfering and causing friction.
It may be the type of shoe you are wearing. Many people also have a bony prominence called a pump bump that may contribute to this problem. Having your feet and shoes evaluated by a Podiatrist would be helpful.
Many times blisters are due to friction against an outside object, which is in this case the heel counter. It is likely that your foot structure is the force responsible for the friction against the shoe counter. I would have it checked out for possible shoe recommendations and to rule out other underlying conditions that may predispose you to developing blisters.
If the blister is localized on the outer side-back of the heel, there may be an underlying bone spur on the heel that is rubbing on the back inside of the counter (back of your shoe). The friction, pressure, or shearing forces exerted on the skin on the back of the heel can result in micro trauma-injury at the affected area, thereby causing a blister(s), inflammation, redness, swelling, and pain to develop.

Treatment: protect the affected area(s)-tissue, reduce pressure. Band-Aid by Johnson & Johnson manufacture (ex. Band Aid Heel Blister Bandage or Band Aid Blister Ampoules); wearing open back sanders, wearing a soft back counter shoe; over the counter orthotics may help to control the function of the foot on ambulation. Topical antibiotic medication covered with a regular flexible cloth band aid applied to the affected area until the area has healed. Seek medical care from a foot specialist if symptoms don't improve with conservative care.
