Retailers may use 3D foot scans, footbed scans, a foot-measuring tool, or pencil and paper when discussing skate size. This guide explains what those methods record and how they fit into a fitting appointment. It does not rank them or claim that one method is better or more accurate than another.
Boots are best fitted in person by a qualified shoe fitter with skate-fitting experience. The assessment should cover the size and shape of both feet and how the actual boots fit on them, rather than relying on a measurement, scan or size label alone. Even boots carrying the same size label can vary in size and shape enough to make a difference to the experience of skating. Use the measurements to support that assessment; see checking skate fit and choosing your skates.
3D foot scans
A 3D foot scanner records a digital representation of the foot's external shape. Depending on the system, the report may include length, width, instep height, arch height and other dimensions. The retailer may use it to discuss stock sizes, fit families or a custom-boot order. For example, Bauer describes using its FitLab foot scans for custom skates, while Superfeet describes the dimensions recorded by its 3D scanning system.
Follow the operator's instructions about stance, socks and foot position, and ask to see the results for each foot. A suggested size or model is a starting point for trying boots on. The fitter still needs to assess how the selected boot holds your heel, accommodates your toes and instep, and feels when it is laced and you adopt a skating stance.
Ask which brand, model or fit system a recommendation relates to. A scan result for one boot range should not be treated as a universal size across other ranges; manufacturers' sizing explains the different labels.
Footbed scans and pressure measurements
If a retailer offers a “footbed scan”, ask what is being recorded. Is it an image or shape measurement of the underside of your foot, or a measurement of the pressure beneath it? A shape scan and a pressure measurement are different types of information; the name alone does not tell you that both are included.
Some systems combine them. Superfeet describes a 3D foot scan and a separate dynamic pressure mat used while walking. Sidas also describes pressure distribution, arch information and the interpretation of results as part of its Feetbox process. These are examples of the systems' functions, not a comparison of their accuracy. Superfeet's scanning process, Sidas' explanation of Feetbox information.
The information may be used when discussing footbeds or insoles as well as boots. Ask whether the measurement was taken standing still or moving, what the report means, and how it relates to the proposed skate. A footbed recommendation and a boot-size recommendation answer different questions. The fitter should check the boot with the footbed or prescribed insert you will actually use.
Foot-measuring tools
A shop may use a sliding length gauge, a Brannock-type device, or a skate manufacturer's own measuring tool. What is measured and how the scale is marked depend on the device.
The Brannock Device instructions describe heel-to-toe length, heel-to-ball length and width. A simple length gauge may not record all three. A shoe-size reading also needs to be distinguished from a skate manufacturer's size marking.
Edea's measuring guide describes a device showing both millimetres and Edea size markings, with instructions for socks and stance. Ask which scale is being read and whether an allowance is already built into it. Do not add a generic allowance to a manufacturer's gauge reading yourself.
Both feet should be assessed. Record which device and scale were used alongside the result, so the fitter can interpret it later rather than treating every number as the same kind of measurement.
Pencil and paper
A tracing records the outline of each foot on paper. Length and width can then be measured from the drawing. A retailer or manufacturer may ask for this before an appointment or as part of a remote discussion.
Use the instructions supplied by the fitter or boot manufacturer. For example, Edea's tracing procedure calls for a hard surface, bare feet, weight on the foot being traced, and another person holding the pen upright. It asks for both foot lengths and widths, with the heel and furthest toe identified. If sending a copy, keep it flat and include the written measurements so its scale can be checked. Edea's foot-tracing instructions.
A paper outline records the foot in the position in which it was traced. It is not itself an assessment of how a particular boot fits. Note whether socks were worn and which measuring instructions were followed when sharing it with a fitter.
From measurements to boots on your feet
Whichever method is used, the next step is an in-person assessment of the actual boots with a qualified shoe fitter who has experience fitting skates, including the relevant brands and models. A member of the Society of Shoe Fitters is one example of someone with a footwear-fitting qualification; ask separately about skate-fitting experience.
The assessment should include both feet's length, width, depth, volume and heel shape, together with heel hold, toe space, pressure points and the fit when the boots are laced. Bring your skating socks, any prescribed inserts and your current boots, and explain your skating activity and any existing fit concerns. Checking skate fit covers the boot-on-foot part of that process.
The size label does not make two boots interchangeable. Brands and models can have different shapes, and individual pairs can vary too. Graf explicitly notes pair-to-pair size variation in its figure-skate catalogue, page 31. Small differences in heel hold, toe space or pressure can matter to the skater. Assess the pair you will use, including when replacing boots with the same marked size. Edea likewise describes measuring, trying on and adjusting as distinct stages of its fitting process.
If boots are painful, ask for a proper assessment rather than accepting that a scan or measurement proves the fit is right. The guides to breaking in ice skates and dealing with foot pain explain why pain should not simply be dismissed as break-in.
Questions to ask at an appointment
What does this method record, and have both feet been assessed?
Are these foot measurements, shoe-size equivalents or boot-size markings?
Which manufacturer, model and fit does the suggested size refer to?
Will you assess the actual boots on my feet with my skating socks and intended footbeds?
What shoe-fitting qualifications and skate-fitting experience does the fitter have?
For size-label comparisons, continue to manufacturers' sizing. If considering a used pair, also read buying second-hand skates. To discuss individual support, Ask an Expert lets you request a connection with a supporter; confirm their fitting qualifications and skate experience before arranging an appointment.
