Blisters with netballer

    have a 13 year old female patient with excessive pronated feet. Prescribed orthoses. Ok with normal running and walking but when playing netball is geting blisters in arch areas of both feet.

    I am looking at dropping the arches in both orthotics and perhaps providing more flaring and cushioning of orhtoses covers in MLA.
    I was just wondering if there is anything else I have missed? or could do to help prevent this problem.

    Have you seen the shoes that she wears for netball, are they different, maybe a medial support type runner that makes your orthosis sit too high?
    Is the runner the right size for her, not too broad a fit?

    Make sure the runner is laced up firmly, maybe an ankle lock method of lacing to reduce any shearing/friction type action, it might also be worth cutting a channel in the orthosis along the hallux flexor tendon.

    Had a similar problem with some police cadets training for their physical fitness test

    Yep, I`d probably do the above and check how much the navicular is drifting. Could be a transverse planal dominance thang going on? If it is, then I`d devise an orthoses with a medial flange.

  4. We get blisters from friction - netball very stop start - increased friction.

    So look at ways to reduce friction - be careful with what top covers you use this may increase frction.

    so well placed sports tape when training and playing may do the trick - reduced friction between skin and device.

    2 pairs of socks - reduced friction between device and skin

    and also consider that the device arch height may infact be too low and this is allowing the MLA to change which is leading to the increased friction from skin and device.

    I agree with Michael. In addition to the above, I sometimes find talcum powder helpful in conjunction with the 2 pairs of socks. Correct shoe fit is crucial. The orthotic and shoe must work together as one. Any sagittal plane movement of the orthotic in the shoe is going to aggravate the situation. The heel height, last shape and shank of the shoe will also effect MLA pressure/friction.

    If all else fails though you may need to drop the arch height.

    The blister is in the arch. Where does the edge of the orthotic lie in relation to the blister? If it is at the medial edge of the device then a wider device could solve the problem. Does she have a promenent plantar fascia?

    For personal use, I've used a lower arched device that still relileved symptoms.

  7. Reduce friction: Driclor, vaseline, dual skin socks, gel socks, prophylactic blister dressings, lower friction top-cover on device, reduce arch height of device.

    Thanks for feedback everyone. Wil ltake on board. Still leaning towards a more medial flange and lower arch height. Blistering is on medial edge of device.
    And Simon I don't like flags or U2. Paul Hewson will one day get over himself. It looks like it may take awhile though. Cheers

    I do not do orthotics, I only know a little about them but do know alot about Netball.
    Is the girl left or Right handed? This will have a huge effect on the way she uses her feet in Netball.
    It is an extremely high impact sport.
    The landing foot takes the main bulk of this impact ( Right handed = Right foot) (Left handed = left foot)
    As the landig foot hits the ground landing on the met heads and often the heel of this foot does not meet the ground as the player spins/pivots on this area.
    The other foot is the take off foot and the full foot touches the ground and is used to propel the pivot. and push off again.
    From what you are planning to do eith the orthotics it sounds right to me, but you may need to adjust slightly different fot both feet.
    I hope this helps .

    I'm not sure everyone has the same definition of medial flange. For me, a medial flange is an upward curl at the medial side of the device. This upward curl has to be medial to the plantar medial border of the foot. If not, you will get some serious blisters. You could just make the orthotic wider without the flange (upward curl).
