A recent study investigating the feet of 95 skaters showed that 89% of the skaters were wearing a boot that was between one and four sizes too big.
Wearing boots that are too big allows the heel to move up and down within the boot, it also causes the skater to lace their boot too tightly, causing the foot to rub uncomfortably against the boot, sometimes in several places.
The result is that friction is generated on the foot and ankle and when this force is applied over time, several foot and ankle problems may develop.
Bigger boots also alter the mutual relationship between the foot’s anatomical structure and the boot’s features. For example, when a poorly fitted boot is worn, the foot longitudinal arch doesn’t sit on the boot arch, creating discomfort because the natural arch of the foot is not supported by the arch of the boot.
Also, with bigger boots, the ball of the foot does not sit over the frame axle, resulting in difficulties in spinning and in jumping with an overall reduced performance in all skating elements.
