Buy hockey skates in your shoe size and you will end up with skates you cannot skate in. It is the most common mistake in the sport, and it is not a trap so much as a convention nobody explains: skates are sized about one and a half sizes below street shoes. A size 10 shoe is roughly a size 8.5 skate, and the box looking wrong is the first sign you have it right.

Why skates run smaller
A shoe is designed to let your foot move a little. A skate is designed to stop it. Everything you do on the ice is transmitted from your foot, through the boot, into a quarter inch of steel, and any movement inside the boot is power that never reaches the blade. That is why a properly fitted skate feels tighter than a shoe you would walk in, and why a skate bought roomy for comfort makes edges feel vague and turns feel late.
Sizing down is how manufacturers build that in. The number differs a little by brand, running between one and one and a half sizes below your shoe, which is why the tool above gives you a small range to try rather than pretending one number is exact.
The method
skate size = men's US shoe − 1.5
tiers: Youth up to 13.5, then Junior 1 to 5.5, then Senior 6 and up
We work through foot length rather than straight from the shoe number, using the same Brannock formula as our shoe size converter, so the two pages always agree about what a given foot measures. Women's shoe sizes convert on the Brannock scale, where a women's size runs one above the men's size for the same foot.
Worked example
Youth, Junior and Senior are three different scales
This is the part that causes wrong orders online. Hockey skates come in three tiers, and the numbering restarts between them, exactly the way children's and adult shoe sizes do. Youth runs up to 13.5, then Junior starts again at 1 and runs to 5.5, then Senior starts again at 6.
So a Junior 5 and a Senior 5 are not the same boot, and a listing that just says "size 5" is ambiguous. The tiers are not only length either: Junior and Youth skates are built on narrower, lower volume lasts with softer support, because they are designed for a lighter skater who cannot flex a stiff boot. Putting a heavy adult in a Junior skate in the right length still gives a boot that collapses under them. Always check the listing says Y, Jr or Sr.
Shoe size to skate size
Men's US street shoe on the left. The range is what to try, since the drop runs one to one and a half sizes depending on the brand.
| Men's US shoe | Foot length | Skate size | Try |
|---|---|---|---|
| 6 | 9.33 in | Junior 4.5 | Jr 4.5 to 5 |
| 7 | 9.67 in | Junior 5.5 | Jr 5.5 to Sr 6 |
| 7.5 | 9.83 in | Senior 6 | Sr 6 to 6.5 |
| 8 | 10 in | Senior 6.5 | Sr 6.5 to 7 |
| 9 | 10.33 in | Senior 7.5 | Sr 7.5 to 8 |
| 10 | 10.67 in | Senior 8.5 | Sr 8.5 to 9 |
| 11 | 11 in | Senior 9.5 | Sr 9.5 to 10 |
| 12 | 11.33 in | Senior 10.5 | Sr 10.5 to 11 |
| 13 | 11.67 in | Senior 11.5 | Sr 11.5 to 12 |
How a skate should feel
Length is only half of fit, and the shop test is quick. Standing up with the skate laced, your toes should just brush the toe cap. Bend your knees into a skating stance and they should pull back off it slightly. If your toes are curled or jammed at any point the skate is too short; if you cannot feel the cap at all standing, it is too long.
Then check the heel. It should be locked in place with no lift when you rise onto the balls of your feet, because a heel that moves is the source of both blisters and lost power. Unlaced, you should be able to slide about one finger down behind your heel with your toes touching the front. Anything more than that is too much room.
Width, brands and baking
Width is not on the chart above, deliberately. D is the standard width and EE is wide, but every manufacturer builds on its own last, so the same nominal size in two brands can fit like different boots: some run narrow and low volume, others are cut for a wider forefoot or a higher instep. A general chart cannot honestly tell you which suits your foot, and any page that claims to is guessing. That difference is also why the same skater is often a half size apart between two brands.
Most skates above entry level can be heat moulded, usually free where you buy them. Baking softens the boot so it takes the shape of your ankle and instep over a few minutes, and it genuinely helps with pressure points, a wide forefoot, or a prominent ankle bone. What it cannot do is change the length. A skate that is the wrong size before baking is the wrong size after, so get the length right first and treat moulding as the finishing step, not the fix.
