5.10 Quantum  by dpm | 05/25/2011  5.10 Quantum   “What are
those purple shoes?”  That’s what everyone asks me when I pull
out the new 5.10 Quantums, and I tell them- “They're sick!”  I'm
not a downturned shoe fan- most hurt my feet due to the severity
of the downturn and the lack of stretch in the shoe.  The
Quantum solves both.  A slight downturn and a perfectly stretchy
Cowdura upper provide great fit, and the low volume heel cup
seals the deal.  The Mystique rubber ensures that the great
edging capabilities stick around after countless pitches on the
rock.    Right out of the box, these shoes fit perfectly: super-
snug, but not painful.  The lack of dead air in the heel was a
welcome change from most shoes for me.  Even the laces, which I
normally hate, were awesome.  The ridged laces stay put when you
pull them tight so you don’t have to battle to keep it snug at
every pull.  They also climb amazing straight out of the box and
stick to just about whatever you put your foot on.  They're at
home on anything
