For the life of me, I could not find where the recommended size lace was. I purchased the 34" laces for a size 8 medium width running shoe - 6 eyelets on each side. It's a perfect fit.  I have about 3 inches leftover.  Other than that, my shoes are easy on, easy off - nice snug fit and easily adjustable!  You can't beat them!  Great gift for the runner in your life, someone who has difficulty in bending to tie their shoes or even the seniors!
