I have a DUI TLS350 that has attached boots, I like it and like the boots attached one less thing to loose or forget. But during the time I have had it I notice at times my feet feel floating and I am certain this is why. I have been using fin keepers on the boots to help but was wondering if anyone else has had this issue and if so how have you dealt with it. Again its not a major issue and I manage the bubble fine just curious.
