I read that the color was ruby and somehow thought these shoes were red.  They definitely are a dark pink, for anyone who might be unsure.  Also, these shoes run small.  I normally wear a 7-1/2 and had to return these for an 8.  They are comfortable and the toebox is just large enough to provide some wiggle room for my toes.
Update:  I have had a chance to wear these to the gym a few times.  I usually do the treadmill for 45 minutes to an hour, and I had no sore feet, ankles, knees, back, anything to indicate that the shoes were not supporting me correctly.  I have also worn them walking and hiking.  They have been very comfortable and I have had no issues.  I still wish they were red.  But I get lots of compliments on the color.  And I definitely wanted a change from the boring black/grey/white colors most running/trail shoes come in. Very happy with this purchase.
