    Have tried many things, they wont go away, can barely walk, they are like loonie sized. How do I try to remove them or reduce them?

    Thanks.

    Usually for most blisters it is best to leave them intact. The fluid gently bathes the raw, immature skin under the blister.

    But in your case, perhaps it is best to break the blisters with a pin that you can sterilize just by holding the tip in the flame of a match or lighter. Draining it will reduce the size of the blister, and decrease the pressure transmitted to this sensative area on your heal.

    To decrease the pressure on the area, cut a "doughnut hole" in a piece of moleskin so that the hole encompasses all of the area of the blister as in the above picture. But don't put tape directly over the blister area. Instead put yet another sheet of moleskin without a hole in it over the first to provide a gentle covering to your blister.

    It will take at least another week for the immature skin under the blister to mature. Until then, try to limit the amount of tennis and walking so as to let the new skin heal without experiencing further trauma which will delay healing.

    Don't be surprised if even just a moderate amount of walking around will cause the dressing to loosen. Carry supplies with you to change the dressing if this happens.

    Thick tennis socks like Thorlo 3 can provide more cushioning now, and are a good prevetion for blister formation in the future. I don't know if this was caused by a new pair of tennis shoes, but in the future you may want to break in your new tennis shoes gradually, bringing the old pair to the courts to change into at the first sign of irritation. You may also want to keep some Moleskin in your tennis bag, just in case.

    Good luck!

    Better fitting (narrower heel cup) tighter shoes, or thicker socks? Maybe it's called the HEEL.
    Just kidding, that's a serious impediment to tennis.

    My blister is on the exact place as that guys too, I didnt pop it yet. It looks like a penny is in the back of my toe, its the same round shape and sticks out the same size as one. Not good, not sure what im going to do.

    It'll toughen up in a week and you can resume running and moving.
    Heel cup in your shoes is too wide, or not shaped to your feet. You need smaller sized shoes (mine are 10.5, barely room for pinkie to wedge into the heel area). If you keep using those shoes, use an insole and thicker socks.
    Lots of serious hikers rub vinegar on their baby feet before hiking season, as that seems to toughen up the skin. Takes only twice a day, 2 minutes, for a week to make a huge difference.

    Yeah must be the shoes, I wear size 10.5 but these shoes are the typical wear now. Too wide, too flat bottom, slip on. Cant help. Gotta start wearing my other shoes for this thing to heal.

    So that means that 1 tick pair of socks is better than 2 thin ones?

    I can lay claim to having the flattest feet of anyone. Full imprint when the feet are wet, even when running.
    Arch support and insoles are the blessed comforts of life. I use them for snowboarding, motocross, tennis, and even the hated ....work.
    AND, they make me a hair taller so my 5'10" and 7/8th become a real 5'11".
    Surprisingly, my low and half volleys are not affected whatsoever, as I've forgotten them and played, and still can mishit low and half volleys.

    JUST how flat, you might ask?
    Flat enough for the USArmy to give me a physical disability when I was 18.
    To join at 20, I faked my arch by tensing up, making me taller than 5'11".
    To get out of the Army 13 month later, a Capt saw my footprints from the shower and asked ....who dat masked man?.....or something similar....
    Wierd, but true.

    I seem to have very flat feet, as soon as I get out of the shower, on the mat is my whole foot imprint. Everyone says I run flatfooted.

    My blister has so much liquid in it though it sticks up the width of two pennies, Im not sure if I should pop it out let it heal on its own. Hey LeeD have fun working, now that your wife is back in town tomorrow.

    Geez :oops::oops: thanks a lot, man.
    But she gets in tomorrow nite, so after work in the morning tomorrow, the last tennis day for a while.
    I"m old, ran into a lot of weird situations in the big city. Most old farts have tons of stories to tell, something I learned from hanging out in dowtown SanFrancisco since I was around 8.
    Blister will go dry in 5 days, skin will dry and fall off in a week, and everything hunky dory in 2 weeks.
    Tighten up those laces, next time.

    Why, thank you for the pleasant dreams regarding my immediate future of no tennis, all work, no play, and constantly catering to her wishes...
    And believe it or not, I left the cell inside her car since 3PM! Oh, only 20 odd calls, calls to my friends, almost a call to the police as to my whereabouts...:shock::shock:
    I think I owe her kinda big time........:oops:

    Take a look at all your socks. It should be no surprise that the most wear is at the areas of greatest weight bearing and friction: at the heel and across the ball of the foot.

    Two socks that are threadbare at the heel and across the ball of the foot are not going to provide much of a cushion to your foot.

    On the other hand, the extra thick cushioned areas of the heel and ball of the foot on specially designed Thorlo tennis socks will help prevent blisters. Also, the soft acrylic "synthetic wool" fibers don't compress down or bunch up near as much as cotton socks do.

    Back in high school I ran cross country in the fall, but that is only straight ahead running. As soon as basketball season started, I knew I was in for terrible foot blisters from the sudden starts, stops and changes in direction even though I wore two pairs of cotton socks. Finally, I "discovered" Thorlo tennis socks, and haven't had a foot blister since.

    And to prevent a recurrence don't forget LeeD's other advice for better fitting shoes and replacement insoles (and even retightening/retying your shoes after a short warmup after your laces have loosened a little and your socks are compressed from sweat).

    Bad foot blisters are no djoke. (Oops, sorry about the spelling.:))

    No, the exact opposite. 2 pairs of thin socks are way better than a single thick sock.

    Hey thanks for the reply, most of the wear is on the back part of the socks. I guess I need to shoes, just looking at the back of them now, all the padding is worn off now there is just the plastic, more room for my foot to move. Will look into those insoles and better fitting shoes. Blister seems to be going down now, stilled filled though. Will try two pairs of socks.

    Thanks again.

    yes if your socks are worn through in one spot you should throw them out and replace them. my recommendation for two pairs of socks over one single pair of thick ones is because you can get a similar level of cushioning by doubling up but you get the added benefit of having the extra layer that can slide and reduce the friction between your skin and the inside of the shoe.

    also, as far as socks go, thor-lo's can be a little pricey and it may not seem bad if you're only buying one pair, but think about how many pairs of socks you are really going to need to keep up with how often you play tennis. so if you are buying 6 pairs it can really add up. you can get multi packs of thin athletic socks at tj maxx/marhsall's/target for the less than the price of a single pair of thor-lo's.

    Hey goran, the blisters are not from tennis as I havnt played since last week of Dec. My shoes are so worn at the back but look like new everywhere else, it is caused from walking a few km each day. Thanks will look at the socks.

    Update:

    Blister dried up in 5 days after I got it, took 2 weeks to heel.
    But now the circle where the blister was is a dark purple color skin compared to the light area around it. Wonder how long that will take.
    The two pairs of socks worked good, I got the blister because the insoles I had didnt fit right with the shoes.

    Thanks for the update. I always wonder how things have turned out.

    That dark purple spot is like any bruise - red blood cells [deoxygenated, hence blue/purple like venous blood] that escaped from the capillary bed and is in the tissues. Your body's inflammatory response chemicals (cytokines) and cells (macrophages) will slowly eliminate it over several weeks.
