Most Skate Boots Aren't Leather. Stop Feeding Them.
Every maintenance guide says to condition the leather every few weeks. Look at your boot first: entry-level skates are synthetic, and synthetic doesn't dry out, doesn't crack and has nothing to feed. Conditioner on a synthetic boot sits on the surface, collects dust, and does nothing else. It has the opposite problem anyway - it holds moisture in, so it needs a damp cloth outside and moving air inside. Leather creases where synthetic scuffs.
Every maintenance guide tells you to condition the leather every few weeks. Before you buy anything, look at your boot, because most skates are not leather at all. Entry-level boots are synthetic, and synthetic does not dry out, does not crack, and has nothing to feed.
Conditioner on a synthetic boot sits on the surface. It collects dust and it does nothing else. You have not protected anything — you have given the boot a sticky film and yourself a job to repeat.
A synthetic boot has the opposite problem anyway. It holds moisture in rather than losing it, so what it needs is a damp cloth on the outside and open, moving air on the inside. That is the entire routine, and it costs nothing.
You can tell which you have by how the material behaves when it bends: leather creases where synthetic scuffs. If your boot marks with a fold, keep the product. If it marks with a scratch, save your money and open it up to dry instead.
