See these on Instagram all the time. How do they attach? Are they like around your ankle or
Foot?
Never seen them in real life, but when I re use old Half Cab tongues, I hold the tongue in and it sits down under the other one and I have the laces done right up so the shoe is snug, not just the lower laces with short or cut off ends.
There looks like there is a strap or something, maybe even elastic to go over or under strapped on to the existing tongue which would make sense.
I recall dudes would have to keep putting the old tongues back in to their shoes as they would constantly be coming out back in the 00s if they didn't have them done up tightly.
