I bought some 868s for sale online without seeing them in person first and they are a bit of a disappointment.
I'm pretty sure they aren't any more padded than their slimmer cupsole models which begs the question, "Who exactly wants an shoe that looks like a runner, is more expensive and bulky, but isn't well cushioned?"
The 868 is roughly the size of a Dunk with a rounded toe but feels narrower because of an aggressive waisting near the arch.
The insole is thick but surprisingly un-absorbing - almost like a soft rubber rather than a foam or gel.
The midsole isn't particularly impressive - I'm sure it's thinner than the Reynolds I've been wearing. I wish I had seen this cutaway before buying:
