Replacement Velcro soles for Hammer shoes.
Hammer slide soles allow bowlers to adapt their slide to any approach condition.
They are numbered 2 to 10, with the number 2 sole offering the least slide and
the number 10 sole offering the most slide. The slide soles are oversized and
can be cut to fit any shoe size.
S10 - very smooth, lots of slip for very blunt approaches
S2 - very blunt, little slip for very smooth approaches
