I picked up a couple of pairs of sale Zahba's. One low and one mid. I've been wearing the lows the past two weeks - I skate most days - and my feet and lower legs have been sorer than usual. My feet tend to feel sore initially but that fades throughout the session. My foot doesn't feel constricted, but I initially feel discomfort down the outside of my sole from my mid-foot to the base of my pinky toe. The insole and outsole feel very firm, and maybe they're too firm for my old, tender feet. I was skating Tyshawns, which feel more comfortable, and I wasn't experiencing the pain I am now. Mind you, I've also switched to a new deck and from Thunders to Ventures. The new deck does have more concave and could be part of the problem, if not the primary cause.
