Have used these in my trail runners.
They actually make a nice snug fit that keeps the shoes on the feet.
I am very pleased with them.
Only downside for me is that since the laces are elastic, in order to make sure that footwear doesn't come off in demanding situations, they need to be snugged up some which means that they are stretched a bit. Since they are stretched and being elastic, they want to shorten (i.e. tighten) whenever possible and exert a constant compressive force on the top of the foot. After a while, i find that they become just a tad uncomfortable (NOT painful by any means) and i feel that a minor compromise in circulation might(???) have occured. I base this observation on how good it feels to take the shoes off after 4 or more hours of wearing them and both scratch and massage the top of my feet. Both healthwise and performance-wise, this is not an issue for me. Ok, maybe i'm just a "whining wimp", but i thought others should know, just in case this (possible minor circulation issues) is more of a problem for them.
