it works out i paid £50 for my SF 2. I have 0 complaints about them. Double socking for me was 2 thick pairs of socks where my foot was alot thicker than its normal size, and the boots looked like they were bursting. i still got blisters but i get them on the balls of my feet and big toe but it doesnt bother me painwise. just using them repeatedly broke them in and when they were broke in back to single sock, and they were fine for me. Still im glad i upgraded to mizuno's. Just a perfect complimenting boot i find. Not saying the "tech" works on it with the knuckling panel but it makes it easier to know where you should strike the ball.
