Size guide — our own recommendation
The number on the box is O'Neill's own boot size, not a UK shoe size. We have found O'Neill's boots come up small against the chart printed on the box — by roughly a size and a half. The table below shows what we recommend, rather than what the box suggests. These are also designed for a narrow fit. If you have wide feet, I recommend the C-skins wetsuit boot.
| O'Neill boot size | UK shoe size we recommend |
|---|---|
| 9 | 7.5 |
| 10 | 8.5 |
| 11 | 9.5 |
| 12 | 10.5 |
So if you are a UK 9.5, take the boot 11. If you fall between two of these, we would go up rather than down, as they are already on the snug side.
Neoprene boots should fit like a wetsuit — comfortably snug, with no gap at the end of the toes.
Still not sure? Pop into the Whitstable shop and try a pair on, or give us a ring and we will talk it through.
