💬Description
Them 909 80S Brain Dead Chassis — 80mm chassis from the Brain Dead collaboration.
The 80S chassis bolts to a 909 or 901 boot and turns it into an 80mm skate, keeping a grindable soulframe underneath.
- Sizing: THEM parts follow the shell ladder — check the size chart and match the size of the boot you are fitting to.
- Fits: THEM 909 and 901
📏THEM Skates Size Chart
THEM Skates size by shell, not by EU number. Each shell covers a half-size pair of US Men's sizes, so measure your foot length in cm and match it to the first column — that is the only measurement that cannot lie to you. THEM's shells run roomy compared with most aggressive skates; if you are between two rows, take the smaller shell and let the liner pack out.
How to measure: Place your foot flat against a wall on a sheet of A4 paper. Draw a line at the tip of your longest toe and measure the distance to the edge of the paper — that cm value is the size to match.
| Foot (cm) | US Men | THEM Size | Interior Shell | Cuff | Soulplate | Frame |
|---|---|---|---|---|---|---|
| 24.0 – 24.5 | 6 – 6.5 | X-SMALL | 25.9 cm | 1 | X-Small | 1 (250mm) |
| 25.0 – 25.5 | 7 – 7.5 | XS / S | 26.9 cm | 1 | XS / S | 1 (250mm) |
| 26.0 – 26.5 | 8 – 8.5 | SMALL | 27.9 cm | 1 | Small | 1 (250mm) |
| 27.0 – 27.5 | 9 – 9.5 | S / M | 28.9 cm | 1 | S / M | 1 (250mm) |
| 28.0 – 28.5 | 10 – 10.5 | MEDIUM | 29.8 cm | 2 | Medium | 2 (270mm) |
| 29.0 – 29.5 | 11 – 11.5 | LARGE | 31.4 cm | 2 | Large | 2 (270mm) |
Shell sizing
One shell per two US half-sizes. The liner and insole take up the difference, which is why THEM quote an interior shell length rather than a single size number.
Spare parts
Cuffs come in only two sizes — Size 1 covers X-Small to S/M, Size 2 covers Medium and Large. Soulplates and frames follow the last two columns.
80mm models
The 80mm skates use the same shell ladder and the same cuff sizes, but run an integrated soulframe in place of the street frame and soulplate.
✓ Right fit
Toes brush the end when standing and pull back when you bend your knees. Heel locked, no lift. Snug across the top of the foot once the laces and buckle are done up.
✗ Wrong fit
Heel lifting on a stride, foot sliding forward on landings, or toes jammed hard against the end even with knees bent.
Size Chart Disclaimer. Figures are THEM Skates' own published measurements for the 909 and 901 shells. Fit still varies with foot shape, volume and sock thickness, so treat the chart as a starting point rather than a guarantee.
