EDGE SIZING GUIDE

Find the correct
EDGE frame.

EDGE frames are sized using the physical sole length of your figure skating boot in millimetres.

!

Your everyday shoe size is not a reliable sizing guide. The measurement that matters is the physical sole of your figure skating boot.

ONE Blades EDGE sizing guide showing how to measure the sole of a figure skating boot

MEASURE

Measure your boot

Measure the physical sole of your figure skating boot from the back of the heel to the front of the toe.

Measure in millimetres and follow the centre line of the sole.

Sized specifically for the two smallest EDGE frames.

EDGE REGULAR PICKS

Two sets of EDGE picks matched to your chosen frame size are included with every complete EDGE System.

BEFORE ORDERING

Measure the physical boot

Manufacturer sizing charts are a useful starting point, but they are not always exact.

Boot models, production tolerances and previous mounting work can create small differences. Measuring the physical sole takes about one minute and gives you the most reliable answer.

Do not choose your EDGE frame from shoe size alone.

Always confirm using the measured sole length in millimetres.

CHECK

This is a guide. Your own sole measurement, taken using the steps above, is the number that decides your order. If the two disagree, trust the boot in front of you.

Risport Edea Jackson Aura
How it works: An EDGE frame needs at least its own size in sole length, so this picks the largest frame at or below the sole. Edea and Jackson list sole directly. Risport and Aura list blade only, so sole is estimated as blade + 5mm. Sole under 210mm means no frame fits yet. Estimated sizes near a frame line are flagged to measure. Confirm against the real boot before ordering.
