ONE Blades Frame Sizing Guide

ONE Blades frames are sized using boot sole length in millimetres. This is how figure skate boots are measured by manufacturers, and it is the only measurement that matters when sizing your frame. Shoe size is not reliable.

EDGE Frame Sizing chart with blue boot illustration and measurement guide.

Step 1. Measure your boot

Measure the sole length of your skating boot in millimetres, heel to toe.

Step 2. Choose the correct frame

Each frame size supports boots up to 20mm longer than the frame itself. This allows natural progression for growing skaters without compromising balance or control.

Frame Size Coverage

  • 210mm frame. Fits boots 210 to 225mm.
  • 230mm frame. Fits boots 230 to 250mm.
  • 250mm frame. Fits boots 250 to 270mm.
  • 270mm frame. Fits boots 270 to 290mm.
  • 290mm frame. Fits boots 290 to 310mm.

Wheel Sizes by Frame

Each frame size is paired with wheels designed to preserve consistent skating feel.

  • 210mm frame: 59mm wheels.
  • 230mm frame: 64mm wheels.
  • 250mm frame: 68mm wheels.
  • 270mm frame: 72mm wheels.
  • 290mm frame: 72mm wheels.

Wheel size increases are intentional and maintain stability, glide, and control across all sizes.

Pick Sizes by Frame

Each frame size uses a specific pick designed for correct geometry at that size.

  • 210mm and 230mm frames ship with EDGE Mini Picks.
  • 250mm, 270mm, and 290mm frames ship with EDGE Regular Picks.

2 sets of EDGE picks matched to your frame size are included as standard with every EDGE system. Replacements available from Drop Two.

Important Notes

ONE Blades frames are currently available in five sizes: 210mm, 230mm, 250mm, 270mm, and 290mm. This range supports the majority of junior, teen, and adult figure skaters. Additional sizes may be introduced in the future based on real-world demand and testing.

The 210mm frame supports boots up to 225mm rather than 230mm. The plate of the 210mm frame is shorter than the other sizes, which limits the maximum boot length it can accommodate without compromising balance.

If you are between sizes

Choose the frame closest to your boot length but not longer. If you are unsure, contact support before ordering. We will help you choose correctly.
