I'm riding a pair of 32 Lashed right now.
The ZF1's are stiffer than the Lashed?
I'm primarily a park kind of guy myself. I don't really enjoy freeriding as much as I do hitting a rail or box.
In my opinion the ZF1s are stiffer than the Lashed. But by no means did the stiffness, stop me from going into the park. I don't feel the stiffness of the ZF1 at all inhibited me performance, though it took a little while to get accustomed to. If you were looking for a softer Nike boot, I'd go with the Kaiju.
