Melissa H.wrote a review of Five Ten Siren Lace-Up Climbing Shoe - Women's - 2012 on July 8, 2009
Great shoes - I have a hard time finding a technical shoe that fits my narrow, low volume foot. These are fabulous. The heel fit is great without digging into my achilles tendon and the last is curved enough to provide for precision edging without mangling my foot. Not the most comfortable for slabby, featureless, face smearing and long trad routes, but great for small edges and steep sport routes. I've tried about 10 different pairs of shoes and these are the bomb. I wear a women's 9.5 to 10 in street shoes and bought these in a 9. Perfect.
