Different surfaces can affect traction and control, so it's important to find the right sole plate for the type of pitch, or court, you play on. Firm Ground (FG) sole plates are perfect for ground with natural grass, kept short and dry or slightly damp, but not muddy. Indoor Court (IC) sole plates offer the traction you need for indoor court and outdoor street or concrete play. Turf (TF) soles are designed for use on older artificial pitches, which tend to be shorter and firmer than modern 3G and 4G fields, and those found at small-sided indoor facilities.
