Looks like a great idea, however it will not stay in your shoe as I slips out within a few moments of playing! Please note I always wear high end running shoes that are new and laced up tight and the shoes are only used for live shows and stage never worn anywhere else, and I have many pairs so the are in perfect condition. I am going to try using duct tape and wrap a band of it around the shaker and my sock before I put on my shoes. I would like to be able to use this shaker as it has a good sound! So at my next rehearsal I will give the tape idea a try? Otherwise it is not much good!
