************* READ BEFORE PURCHASING *************<br />First I love Amazon and purchase a lot of products from them.  But every once in awhile I get something that isn't correctly described.  These replacement cleats are that way.  The website describes them as multipurpose but this is not accurate.  The product packaging states<br />* Superior Traction for Synthetic Surfaces.<br />* Designed specifically for synthetic turf, artificial grass, field turf, ever grass, evergreens and turf grass applications.<br />* Reduced profile allows cleat penetration into synthetic surfaces.<br />These facts were not listed in the product description so I purchased these cleats for replacements on my son's football cleats.  He plays on really grass so they as inadequate.  They're too short only 5/16&#34;.<br />Bottom line is - if you play on a synthetic field they should work well.  But they are not for playing on real grass outdoors.<br />Reordering 1/2&#34; cleats from Sof Sole.
