Go and use them 1st. A few hours with no protection will not harm. Have some fun 1st. Then tyre sox. Then get an inner tube ( old punctured 1 will do). Cut two lengths, both as long as the springs. Then cut them lengthwise. Wrap around springs and secure in place with tape. Hockey or plumbing tape, wrapped around the tube, so that it is totally covered. Will lessen damage to springs on a fall.
