A nice pair of boots can complement almost any outfit, but if you have curvy calves, it can be hard to find boots that fit just right. Luckily, if you have a pair of zippered boots that fit your feet well but are a little snug in the calves, you may be able to stretch them out!

Things You Should Know

  • Spray stretching spray in your boots and put them on over a pair of thick socks. Wear them for at least 5 minutes, repeating each day until they’ve stretched.
  • Or, put on a thick pair of socks, slide on the boots, and heat them with a hair dryer for 30 seconds. This helps relax and stretch the fabric.
  • As another option, insert a calf stretcher in the boot. Twist the handle so the stretcher fits snugly in the boot and leave it there for at least 2 hours.

    If your zipper is shoddily constructed, or if it’s not sewn in well, you may damage it by using too much pressure with the boot stretcher.

    Make sure you are using a stretcher designed for the calf of a boot and not one for the toes or instep. A calf stretcher will look tall and thin. [1]

    You don’t have to use a stretching spray, but it will help soften the fabric and you will achieve better results. [2]

    Depending on the style of boot stretcher, you may have a lever or there may be a small wheel in the center. Use these to adjust the stretcher until it fits snugly in the calf of the boot. [3]

    For best results, you want to leave the stretcher in for as long as possible. If you sprayed your boots with stretching spray, you’ll want to leave the stretcher in until the spray dries.

    By wearing the boots zipped up as far as they will go, you will slowly stretch the fabric around the zipper as well as the boot itself. After about 15 minutes, see if you can tug the zipper up a little higher.
    • This is perfect if you only need a little extra room.

    A stretching spray helps loosen the material of the boot. Spray the boot thoroughly, then put on a pair of thick socks and put the boots on. Zip them up as far as you can and leave them on for about 5 minutes. Repeat the process if necessary. [4]

    Leather will take on a new shape when it gets wet, so wearing your leather boots while they’re wet is an easy way to get them to conform to your calves. Just make sure you get the boots fully submerged in the water so they don’t get obvious water marks. [5]

    Put on a pair of thick socks to protect your feet, then put on your boots and zip them up as far as you can. Blast them with your hairdryer for about 30 seconds, being sure to move the nozzle around so you don’t damage the shoes. The heat should help relax the fabric, allowing the boots to stretch around your calf. [6]
    • Leave the shoes on until they cool so they don’t shrink back to their original size.
    • If your boots are made of leather, follow up with a leather conditioning spray.
    • Do not use this method on delicate materials like patent leather.

    Since water expands as it freezes, you may be able to stretch out your boots by filling a plastic bag halfway with water, then placing it in the calf of your boot and freezing it. [7]
    • Thaw the ice for at least 20 minutes before removing the bag.

    You can have a special panel professionally inserted into the boot to widen the calf. You might have to visit the shoe repair shop more than once for measurements and fittings. [8]
    • A less expensive option may be to have the cobbler remove the zipper, then reinstall it along with extra fabric or elastic.

      About This Article

      Article Summary X

      If you need to stretch the calves in a pair of zippered boots, spray one of the boots with stretching spray and insert a calf stretcher into it. Once the stretcher is in place, twist the handle to expand it so it fits the calf of the boot snugly. Leave the calf stretcher in the boot for at least 2 hours, but the longer you can leave it in, the more the boot will stretch. When you’re finished, repeat with the other boot. Keep reading to learn how to widen the zipper on your boots!
