I gave the GoBionic a try. I really liked it initially but the lower part of the leather thing where the laces are attached would rub on my feet when they flex. Having made some bloody blister experiences with a pair of Vivo Evos (the white is upper is still red) at a similar spot I didn't want to take the risk and sent them back.
Now I got another pair of K-Swiss Blade Foot Run for 50 bucks, glued some sole rubber to the lateral forefoot outsole and I'm happy.
