You should inspect your grips often for rips, tears, or stretching of the leather. As you use your grips, the leather will stretch and thin. To ensure your safety, your grips should be replaced when any of the following occurs:
-Your grips shift or move during use. Typically this means the leather has been stretched and should be replaced.
-The leather of your grips overlaps in any area.
-The grips are ripped, cracked, torn or there are signs of the leather thinning significantly.
-The leather has worn smooth and has become slippery.
Grips should be replaced at least every 6 months - possibly more frequently depending on the level of strain and use. Always have an extra pair of grips with you (already broken in) in case your current pair rips, cracks, or breaks during practice.
