Why does Seb (in the final ascent in Hard Grit - black rocks i think) wear two different shoes? Ones an Anasazi & the other is a 5.10 slipper (i think)
Theres a bit in that four from font video where Dave graham has a v10 slipper and a.n.other boot on too, maybe he prefers the heel hooking performance of his v10 to t'other boot?
