Pretty close? If your foot is a UK size 12 and therefore 1ft long that will work, but any variance, say 1cm, equates to 60cm / 2ft across your 60ft.

Incidentally shoe sizes are measured with the size 12 UK being 1ft in length. Each shoe size goes down by one barleycorn which is an archaic measurement equivalent to a third of an inch, so a UK size 11 is 11 and 2/3 of an inch, a UK ten is 11 and 1/3 of an inch, and so on.

I would measure the 60ft using a lifesize printout of Johnathan Edwards 18.29m triple jump world record from 1995 which I keep handy.
