well, seeing as how I only just got into Parkour and have only tried two different pairs of shoes, this rating may not be accurate but here goes:
Price: (on sale) $50
Grip: I thought they gripped quite nicely so I would give them an 9/10 but take that with a grain of salt as I am somewhat inexperienced at this point.
Fit: nothing will conform to your foot better except maybe your socks, and even then I'm not so sure so 10/10
Weight: like wearing no shoes at all. (maybe a slight exaggeration but you get the point) 10/10
Padding/cushion/shock absorbency: at the ball of the foot there is no padding that i noticed so good landings are a must, at the heal there is considerably more but its still hard. 5/10
Durability: seems like it would be good but I haven't had them for more than a week or two yet. ??/10
if I have left anything out, and I probably have, let me know and I will fix it.
PS I have ordered a pair of Ariake's and will gladly post a new review after wearing those.
