I actually just got off the phone with Ryan at Etonic. According to him, these r still a couple months off. At this point the shoes r still in the R&D phase, theyre trying to make sure all of the kinks r out of the shoes b4 getting them on the market.
From what Ryan said, this is going to be the first "fine tune" heel system. Its a turn & crank style heel, its completely fixed to the shoe, but the front part of the heel has 3 different rubbers to choose from. Its on a "wheel" so to speak & if u crank it 1 way, u get more of the rubber that slides more, & if u crank it the other way, u get more of the rubber that sticks a little more.
Couple this fine tune heel with the fact that theyre giving 5 different slide soles, & these seem to be the most versatile shoes ever produced.
Until i actually get a pair on my feet, this is all the info i ahve, & as far as i know, all of the info that is available.
