I tell ya what... this is one of those "Why the heck didn't I think of that!!!" products.  Simple design but wow!!!  WELL WORTH THE MONEY.  The design is nice and worked well with my daughter's shoes.  I tied the laces pretty loosely on purpose this morning and placed the Snap n Step Locks on.  I'll be darn.... shoes are still tied!  LOVE THIS PRODUCT and will be telling everyone I know.
