I just bought some Dainese in boots, however, i have a very old style Dainese race suit, it does not have the velcro in the bottom of the suit pant.

Any ideas on how I can get these items to work? I have thought about stitching the opposite sex velcro onto the inner lining of the suit, but will this destroy the lining? I've never used in boots before and don't really know how much the boots pull down the pants during a turn; I'd imagine quite a lot?
