Oh man is this topic gonna explode with silliness.
I've got pretty narrow/low-volume feet. I've been climbing in some Defys at the moment. The length is good and painful, but I slide around in them sideways. I've tried on tons of shoes and they all seem too wide.
I've been thinking of trying on the women's versions to see if they fit better. Anyone have luck with wearing women's shoes?
Take a close look at the feet in climbing photographs. You'll notice the genderization of shoes is not hard and fast. When I got into climbing, I had narrower feet, and the Lady Katana's fit perfectly. I still have them, but my arch has collapsed more and my feet have widened so men's Sportiva's work just fine now.
That said, you'll find that Evolvs and 5.10s run pretty wide, and Sportiva and Scarpa can run both narrow and wide depending on the model.
Try them on, but don't limit yourself to just men's shoes. Also, who doesn't love a little color on their feet!? I sort of miss the baby blues of my lady katanas.
When I worked at a climbing gym we sold quite a few pairs of 5.10 Siren shoes to guys with small feet. Apparently a bunch of people have been doing this as well so 5.10 came out with a more manly maroon color instead of the baby blue. Everyone I know with these shoes loves them.
I'd also look at the 5.10 Coyote's, they run a bit narrow as well.
As for the Scarpa Techno's, I have a pair and disagree with the comment about them running narrow. They seem decently wide to me.
I've definitely owned a couple of pairs of women's climbing shoes over the years. As of late the lace up Katana has been great and if you're having trouble finding Sportivas check out the Scarpa Boostic. The Boostic won't be a great all around shoe but for edging and steep climbing it's been fantastic so far... oh and it's definitely colorful.
I also liked the the Defys fit lengthwise, but had too much volume above toes and to the sides. Electras, the women's version of Defys, was not available in the "painfully comfortable" size, but Rockstars were. So, I got me Rockstars Even though the color might be a little girly, the smell is definitely manly.
