Does anyone have any recommendation on sports insoles? I usually buy relativly cheap trainers £20-£30 my last pair was some reebok indoor court trainers and use some well padded socks (1000 Mile Racket Sock) which I find quite comfortable. I also want to change the insoles in my trainers. I have been looking on the net and found some called: Sorbothane Double Strike Insoles http://www.fitnessfootwear.com/p-1160-sorbothane-double-strike-insoles.aspx anyone tried these.
