Build a real practice studio at home for less. The ProStep Dance Floor Kit pairs our best-value reversible marley with cushioned, interlocking subfloor tiles and seam tape, so you get the surface and the shock absorption in one box. What's in the kit ProStep Reversible marley, pre-cut rolls with a matte grip side for ballet, jazz and modern, and a faster glide side for hip-hop Cushioned subfloor tiles, interlocking 2' x 2' tiles in your choice of 3/8" or 3/4" thickness Mat tape for sealing seams and securing edges Pick your size and cushion Kit size Marley Subfloor tiles Tape 5.25' x 10' (52 sq ft) 1 roll @ 10' 10 1 roll 10.5' x 10' (105 sq ft) 2 rolls @ 10' 25 1 roll 15.75' x 10' (157 sq ft) 3 rolls @ 10' 35 1 roll 15.75' x 15' (236 sq ft) 3 rolls @ 15' 49 2 rolls 3/8" or 3/4"? Both cushion your landings over hard floors. Choose 3/4" for the most impact absorption, for concrete slabs, or for dancers putting in serious daily hours. The marley overhangs the tiles so the taped perimeter forms a low ramp, with no trip edge. Built for soft-shoe styles Ballet, jazz, modern, contemporary, lyrical and hip-hop. ProStep is a soft-shoe marley: for tap, flamenco or Irish hard shoe, choose the Rosco Adagio roll or Tap Dance Floor Tiles instead.
