Put these on a pair of new balances size 10.5.  The installation is easy and they work really well.  Only two critiques-  the top of the bracket that holds the shoelace on the inside of the shoe sticks slightly over the top of the shoe so they are barely visible.  Instructions say to leave an inch or so of extra lace after trimming.  The extra would bunch up and rub the sides of my feet.  I ended up cutting off most of the extra and its much better.
