Hey

My friend told me that spring bac insoles only add the 2-3" to your vert if you jump once then straight away jumping up again will give you the extra 2-3" but you won't get the gain on the first jump. Its a bit confusing but thats what he said.

IS this true?? as if it is i wnt get them

thanks
