Eventually, sure.
But since the knot is kinda flat, and since the rubber is flexible, and since the knot tends to be in between your toes, it’ll last WAY longer than you think.
Many Xero Shoes customers have put thousands of miles on their shoes without wearing out the knot.
And, we give you enough lace that when/if the knot does wear out, you can just pull another inch of lacing through the huaraches sole and make a new one.
You can buy extra laces for just a few dollars.
