Not sure how available these are, but got a pair, and I love the upper. It adds an ounce or two, but fits my foot much better then the lunar racer with the flywire upper.
Anybody know if these will be come available for the masses anytime soon? I did see a new Streak is on the way, and the new Streak XC is out as well. Does anyone know of somebody that has Lunar Mariah stock? saw some on ebay...thanks again.
