All-Star Dryland Flooring Tiles were designed specifically for hockey training, while the Multi-Sport Tiles were designed for a wide variety of sports, including hockey.  The Dryland tiles provide an ice-like surface for stickhandling, passing, and shooting. The smooth surface allows for a natural puck glide that you simply can't find on most "off-ice" surfaces. The Multi Sport Tiles have a textured surface that provides a better grip for running, jumping and playing a wide variety of sports such as ball hockey, basketball, tennis, volleyball, and much more.
Note that regular black pucks do not not slide very well on the Multi-Sport Tiles, but the HockeyShot Extreme Dryland Puck and Dangle Puck 2.0 slide well on these tiles. While there are several other differences, some of the main differences are the size (18" x 18" Dryland Tiles vs. 12" x 12" Multi Sport Tiles), the connections (symmetric for Dryland Tiles, directional for Multi Sport Tiles), etc.  To see all the features of each product, make sure to visit the respective product pages.
