Extend the life of your wetsuit upper / rubber sole rock fishing shoes with Kold Kutter 3/8 studs, Pack of 30
30pcs is enough for a pair of shoes (5 in each heel and 7-10 on each front)
Tested on Sydney area rock platforms over 6 months catching Luderick / Blackfish, Bream, Kingfish, Bonito etc.
Find a sold piece of rubber where a spike was not present and using a 1/4" socket on a screwdriver to screw in the studs is the easiest method, (you can use a large flatblade screwdriver, but a 1/4" socket is 10 times easier)
