maybe you tried them newly - it´s a real tough construction but maybe the foam in the strap (there is some padding inside !) as well as the strap band itself widened a bit - as it does with other straps .. you´ve two screws for adjustment on both sides, so it should fit after one re-customizing ! I´m totally stoked about the new feeling, board control is of another world !!
