Create a measurement record you can repeat
Before selecting a size, find the measurement procedure published for the exact model you are considering. Record left and right foot length in millimetres, width if requested, the socks used and the date. Keep units explicit. A value written as “26.4” without centimetres or millimetres is an avoidable source of confusion when you send questions to a shop.
Follow that procedure carefully and repeat the measurement if the result changes noticeably. Keep both results rather than averaging two feet into one number. If the chart asks for a dimension you have not measured, mark it missing. Your worksheet should make uncertainty visible, not produce a false precision score. This is preparation for fitting, not a way to determine a skate size remotely.
Use the chart for the exact model and version
Roces publishes separate model size tables based on foot length. Use the relevant table rather than assuming one brand-wide conversion. Record which chart you used, its units and the model name. Ask whether it describes measured feet, a recommended fit range or a nominal size conversion. These are questions for the manufacturer or fitter when a table is unclear.
Do not silently add an allowance taken from another brand’s guide. Nor should you copy a friend’s shoe-to-skate size adjustment. Keep your usual shoe size as context, alongside the actual measurements. The final choice also needs an assessment of shape and retention, which a length table alone cannot supply.
Separate the shell and liner questions
Ask which shell size group the candidate uses and which liner is supplied in that exact version. If comparing two listed sizes, ask whether they share a shell or use different shells. If you intend to replace the liner, get compatibility and fit advice for the complete combination, not just for two labels bearing the same number.
During a fitting, describe heel movement, toe position and any pressure location in plain terms. Ask the fitter which closure settings to use for the comparison. Powerslide’s manual warns against skates that are too large or too small. Do not assume persistent painful pressure will disappear or compensate for poor retention by overtightening. Stop the fitting and ask for help if the fit feels wrong.
Write an illustrative shop brief
Imagine your repeated measurements are 263 mm left and 266 mm right. Your brief can read: “These are my measurements using your requested procedure. I am comparing model X, versions A and B. Which current chart applies, and do the candidate sizes share a shell?” Those numbers are illustrative; they do not imply a recommended size or extra clearance.
Add a specific observation if you already own skates: “Heel moves when I bend into my skating stance; tightening the upper buckle has not answered the question.” That gives the fitter a problem to inspect. A request for “one size smaller because a video said so” offers much less useful information and can conceal a different shape issue.
Keep the fitting decision separate from a public review
Before ordering, check the seller’s current fitting and return conditions, particularly whether indoor try-on or adjustments affect returns. Obtain a clear answer about any planned heat moulding; never treat every shell or liner as heat-mouldable. Follow only the instructions for the exact eligible component. Save the agreed size and model with the fitting notes.
After appropriate fitting and equipment checks, start with controlled rolling and stopping in a suitable space, wearing a helmet and appropriate protection.

Quick answers
Should I automatically buy aggressive skates one size smaller than my shoes?
No. Use your measured feet and the exact model’s chart, then resolve shell, liner, shape and retention questions with the manufacturer or a qualified fitter.
