Skate Smell Isn't Dirt. It's Water.

The smell is moisture and bacteria, not grime - which changes what fixes it. A deodorising spray on a boot that never dried masks the symptom and leaves the cause sitting in the foam, and it will be back by the next session. Dry first, properly, tongue forward and air moving. Then, if there's anything left to treat, treat it. Doing it in the other order is why the problem keeps coming back.
Skate smell reads like dirt, so people treat it like dirt. That is the mistake. The smell is moisture and the bacteria living in it, not grime — and once you know which one it is, the fix changes.
A deodorising spray on a boot that never dried properly masks the symptom for a session. The cause is still sitting in the foam, wet, doing what it was doing before. It comes back, and it comes back faster each time, which is how people conclude that their skates are just like that.
So the order matters more than the product. Dry first, properly — laces loose, tongue forward, air moving through the whole boot, out of the bag. Then, if there is anything left to treat, treat it.
Doing it the other way round is not a small inefficiency. It is the entire reason the problem keeps coming back, and it is why the answer to a smelly boot is usually a habit rather than a purchase.
