AHHH I love these shoes!
Can't emphasize enough how great these are for edging. These are my shoes of choices for multi-pitch trad. After a break-in period, these are completely comfortable to wear on longer routes. Yes, you should seamgrip the rand some parts of the rubber are flapping off on mine. I normally wear a size 4 women's Katana and got these in a women's 4 also. They feel great, especially because they don't have that aggro arch like the Katanas. Because of the tiny size I got, I noticed that they don't really cover up my ankles completely. Definitely a stiffer shoes, not so great for sporty smearing action. These are the only shoes that don't hurt my feet when jamming them in wide cracks.
