I'm just getting into climbing and am purchasing my first pair of shoes. Unfortunately, these shoes don't fit, so I can't say much about how they function because I'm returning them. But I'll mention sizing, because this is what I was trying to find when I was ordering.

I wear a size 8.5-9 (usually 39 European) in women's street shoes. I ordered a size 39 in the Scarpa Marathons, but they're too small - mostly in the big toe area. I think a 40 would probably fit me best. The heel also comes up a bit higher than I think I'd like, so I'm not sure they'd fit right if they were the right size. For comparison, I ordered a 39.5 in the Scarpa Tifosi and they were probably a whole size too small. If you're trying to compare to sizes in other brands: a Montrail Splitter 40 (womens) fit perfectly and a Five Ten Anasazi 8.5 (41.5) was too small in the toe (I think a 42 would have done it).

Scarpa shoes are made in Italy and they seem like they're very high quality. (For reference, Five Ten is made in USA and the Montrails are made in China - boo). Reviewers on Sierra Trading Post noted that these shoes stained their feet yellow, which I would be a little worried about, but I guess if the shoes are comfortable it's worth it.

Out of the box these shoes are tight, but thanks to the leather uppers they will eventually break in. I also wear a 10 (43.5) and it has taken several weeks for break in, but now I can go all day. It might still be a good idea to go 1 size larger then normal...best to try on 1st? These shoes work great (I climb 11's) and I found them for just over $50 on sale....I do get strange looks due to the unconventional heal design. I wouldn't use them for walk offs though.

Size was definitely mis-marked. At least 2 full sizes too small. Was supposed to be a men's 10 and was more like a men's 8. I decided to keep them so I will have a smaller shoe when I take people top roping. There were no more in my size. The price was very good and quality appears to be good.
