ONE Blades Frame Sizing Guide
ONE Blades frames are sized using boot sole length in millimetres (mm). This is the same measurement used by most figure skate boot manufacturers. Do not choose your size based on shoe size alone.
Step 1. Measure your boot
Measure the sole length of your skating boot in millimetres. Or check the size label inside your boot or on the sole if it lists mm. If in doubt, measure heel to toe on the outsole. This number is what matters.
Step 2. Choose the correct frame
Each frame size supports boots up to 20mm longer than the frame length. This allows natural progression 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.
Stopper Sizes by Frame
Each frame size uses a specific stopper designed for correct pick geometry at that size.
210mm and 230mm frames use the EDGE Mini Toe Stopper.
250mm, 270mm, and 290mm frames use the EDGE Regular Toe Stopper.
Two full sets of the correct stopper for your frame size are included as standard with every EDGE system. Replacement stoppers are available separately in the shop.
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.
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.
