leg band problem

my conure kiwi always gets his back toe stuck in his leg band, everytime i take the toe out of the leg band it gets stuck again in a couple of days, it's annoying cause kiwi doesn't stand still and i'm afraid to hurt his leg.any1 got any suggestions??

Is the leg band too loose? Don't make it so tight that it's uncomfortable, but if it is large enough to get a toe stuck in there, maybe it's the wrong size?
