I gotta be honest, I rolled with the insoles for a while, had them moulded and everything.
But I bought after market insoles and there's was a substantial difference in the feel in a good way. Much more shock absorbing and just all around more comfortable. Anatomically speaking, the right insoles really take the abuse that your knees would otherwise suffer. If you're content, I guess its not necessary, but as someone riding since I was six - that's 15 years - I would really recommend a pair.
