Fitting recomendations:

- Wear (preferably thick) socks covering your anckles.
- Make sure the liner (inner boot) is well in place.
- Don't tighten the buckles too much ! The sole base being as wide as normal shoes, Kangoo Jumps rebound shoes are very stable and don't need much anckle support.
- Your toes must touch the front of the liner. You should feel a little tight at first. The lining will adapt to your foot and give in where necessary.
- If you feel too tight, try to remove the inner sole of your liner.
- you need to hear a "click" when closing each buckle to the right (snaped) position. If you can't get the "click" it means you are trying to close your buckle too tight. Release it a bit and try again. Sometimes the buckles are more difficult to close when they need oiling: lift the buckle, and rub the inside with your finger. The moisture of your body is enough for the oiling!
