Air Max 1 laces usually run any where from 50” - 51” in my size 12's. I recommend you take the stock laces out and measure them with a tape measurer to get the most accurate length. Also, better to go with the longer length so I get 54".
Anybody with other or better lace shops feel free to chime in.
