    Spot heating liner using wax iron (intuition type)

    I have some heat moldable liners in my Dynafit Hoji Pro tour that fit really well except for at the ankle bones (medial malleolus). Itís fine for some hours but after a full ski day itís getting beat up. Iím trying to find out a way to adjust only that area. One idea is to use a waxing iron (got a digital one with good temperature control) and a tennisball to squeeze compress the liner at the ankle bone . Does that seem like a good idea?
    I spot adjusted the toe of some Garmont liners using a heat gun back in the days, it worked, buts itís a risky business.

    I've never tried using an iron for liner molding - seems like a good way to melt a liner. Heat gun works well.

    You don't have access to a hair dryer even?

    Direct contact with an iron seems like a very bad idea.

    I say give it a go, but you want heat on both sides so maybe drop the tennis ball in a fryer for a few seconds first.

    Get a very small ‘microwaveable heating pad’, carefully increase heating time until it’s hot but not smoking hot, drop into the area of the liner you need to remold for a full ten minutes.

    Had worked well for me for many years and many liners. Often I’ll need a bit more room in the toebox for example.

    Or go buy a set of knee high womenís hose. And a bag of rice
    Fill stocking with enough rice to fit in the area you want molded
    Microwave rice/sock till itís real hot - depends on volume of rice and microwave power. Prolly 3-6 minutes if just size of tennis ball.

    Then follow froriderís instructions above

    Oh yeah, after the ten minutes remove the rice bag and insert your foot (without a sock would be good, but otherwise use the other stocking you just bought)

    See https://intuitionliners.com/home-fitting/

    Same principle as froriderís method, just a likely cheaper heating medium. Iíve used the same sock of rice for ten years.

    Use a heat gun or hair drier.
    Use a heating pad.
    Use anything other than a hot waxing iron and direct contact. Maybe, MAYBE through some layers of towels. The minimum temp on waxing irons is listed as 100C or 212F. So yeah.
    No longer stuck.

    back in the day I was at Intuition factory outlet in Vangroovy and I watched Crystal the fitting guru spot heat a liner, she spot heated with a heat gun and then rubbed the spot with something blunt like the end of a screwdriver and she said only do this once

    but you can always e-mail or phone the intuition people eh

    A hot iron on plastic sounds like a brilliant idea

    Maybe try a lighter or matches next

    Those microwave pads are filled with various things…flax seed, rice, whatever. The main thing is to find one small enough to be useful for a boot liner.

    I keep my foot i there 15 mins and if possible go outside so they cool off faster

    Agreed. We have a bunch of those MW heat pads, just none small enough to fit just in the ankle pocket.

    I have like three pair of the intuition home fit kits. Have made up three bags of rice with them - one for whole boot, one for tongue and one for ankle pocket.

    Never thought about standing in the boots outside to cool ‘em off faster.
    But that would deprive me of the extended agony that is boot fitting…

    word of advice: it's worth using a new sock and not a used sock.

    Also if you have a problem area, I like to put some foam around that area on my foot when I put my foot back in the boot to help emphasize that area and further pack it out/mold it.
