Mounting your ONE Blades EDGE for the first time looks intimidating until you do it once. The full demonstration is in the video below. The reference facts and the mistakes worth avoiding are below that.
Quick answer
To mount EDGE to figure skating boots you need the frames, the supplied screws, your boots, a 2.5mm drill bit, a marking tool, and a drill. Find the boot centre using two reference points front and back, align the frame flush with the front of the boot, mark four holes, drill at low torque, fit four screws, skate-test, then fit the remaining two. Full process takes about 15 minutes per pair once you have done it before.
Tools and specs
- Drill bit size: 2.5mm
- Drill setting for screws: low torque, around setting 3. Never full drill mode.
- Mounting holes per frame: 6 total. Fit 4 first, skate-test, then fit the remaining 2.
- Initial 4-screw pattern: 2 at the front (closest to toe), 2 at the rear (closest to heel)
- Screws supplied: included with EDGE
- Where to drill: outside if possible, to manage dust and fragments
The mount in 10 steps
- Find the boot centre at the front using two equal-distance reference points on a measure
- Mark the front centre with your pen
- Repeat at the rear of the boot, mark the back centre
- Connect the two centre marks to confirm the line is straight
- Align the frame flush with the front of the boot, rear lined up with the back centre mark
- Use a pointed drill bit or pen to mark 4 mounting holes (2 front, 2 rear)
- Drill the 4 holes at full drill speed, holding the bit perfectly straight
- Switch the drill to low torque (around setting 3)
- Hand-start each screw, then drive at low torque, leaving slightly loose for adjustment
- Confirm placement, tighten fully, fit wheels and picks, skate-test before fitting the remaining 2 screws
The video walks through each step in detail. Use it for the demonstration, use the list above as your checklist while you mount.
Common mistakes to avoid
The errors I see most often when skaters mount EDGE for the first time.
Leaving the drill on full drill mode for the screws. The most common boot-damaging mistake. Always switch to low torque before fitting screws.
Leaving your drill on full drill mode while fitting screws will ruin your boots. Always switch to low torque before screwing in.
Eyeballing the centre instead of measuring. Two minutes with a measure prevents an off-centre mount that ruins everything else.
Drilling all six holes before testing. The four-then-test-then-six method exists for a reason. Skipping the test means committing to the placement before knowing if it is right.
Using the wrong drill bit size. 2.5mm is correct for EDGE. Larger creates holes too wide for the screws to grip. Smaller makes screws hard to drive.
Going too fast on the drill. Slower drilling produces cleaner holes and reduces the risk of the bit slipping.
Mounting the frame too far back. Flush with the front of the boot is the reference point.
A few things the video does not call out explicitly
Smaller boots are harder to mount. The frame width is fixed by the wheel width, so on a 220mm boot the frame fills almost the full sole width. Take extra care on small sizes.
A drill bit extender is worth having. Three different lengths from Amazon for a few pounds. Useful when the screw needs to go deep and standard bits get stuck.
Drawing a line down the centre of the boot is unnecessary. Two centre marks (front and back) give you everything you need without marking the rest of the sole.
The skate-test matters. The four-screw mount is deliberately temporary so you can adjust before committing. Run the test on a smooth indoor surface. Rough surfaces mask placement issues.
Final result
Both frames mounted, four screws each, ready to test. Once you have skated on them and you are happy with the placement, fit the remaining screws and the mount is complete.
