KR Cruiser Smooth Triple Roller offers space to store 2 pairs of shoes or more accessories instead. It also includes retaining straps to secure the bowling balls.
Would work well for local travel in car, but must be kept level. Bowling balls not secure in bag. Wimpy velcro (between and on top) to hold heavy bowling balls does not work. Inside of bag was completely messed up (not torn or damaged, just jumbled up) after flight to Reno. Shoe compartment is huge but could use some sort of separator between shoes and accessories. Everything moves all over. Side compartment rather small compared to rest of bag.
