Like skiing, ice-skating requires precise balance and stable control of the blade for good technique and any lower limb dysfunction or alignment can interfere with this. Blades are not flat, but have a slight concave shape in the longitudinal direction. The blade is traditionally in a position along the long axis of the foot (from the centre of the heel to the second toe). There needs to be a balance between pronatory and supinatory forces about the blade the position of the subtalar joint axis may have profound effects on skating ability. It is assumed that the rocker or balance point of the blade should be directly beneath the STJ axis and not necessarily running along the long axis of the foot.
Professional skaters could be considered at greater risk for fungal infections of the foot (wear occlusive skates, sweat saturated socks during several hours of training, sharing gym facilities), however Mohrenschlager et al (2001) found no cases of tinea pedis in one professional ice hockey team.
Skate fitting problems:
Aggravation from a retrocalcaneal exostosis or accessory navicular are common problems due to the need for a precise fit of the skates. These can be accommodated with padding in the skate.
Malleolar bursitis can due to constant friction (normally no bursa in this area, but adventitial one can develop) boot stretching; padding; aspiration; surgical excision
Need a low bulk grind to fit orthoses into skates.
May need to cast foot slightly pronated for orthoses more subtalar joint motion may be needed to bank around turns.
