I do recommend buying a half size up. I find they seem to shrink/form to my foot. It's nice in terms of getting a foot-hugging experience, but my first pair I had to trade out for a bigger pair because they were starting to become too tight. I should say, though, that it may be because I started out running in them when I started barefoot running and my feet have overall grown a bit from gaining muscle. My second pair started out feeling HUGE and seem to have become much more form fitting, though.
- compared to VFFs, you're looking at a much more conventional looking shoe - you can wear whatever cheapo socks you already have and don't have to spend money getting uber expensive thin toe socks
- very comfy
- good grip in mud
- easier to fit than VFFs, and you can find it locally (my local Dick's Sporting Goods carries it), thus you can try it on and make sure it's the one you want. I do live in kind of a small area, though, so it's not so easy to find Vibrams around here.
- If you have weird shaped toes (that wouldn't fit in a VFF toe shoe well) you can still wear them.
- Easy to wash and because I can wear them with socks they don't get as stinky as my VFFs
- There's not much fabric or padding to them so they dry really fast... great if you're doing, say, a mud run.
- I'm wearing out the sole running on asphalt. I guess this is normal, but it happened sooner than I expected.
- the laces don't come up as far as other shoes might so if you have very small heels/ankles or you are running in thick/deep mud you may have some sliding-out problems
- Weird elastic on the rear of the collar - seems like almost all of their women's barefoot shoes have them. I was skeptical of this at first, but it turns out it's not a big deal at all - the elastic is fairly stiff so it really just moves with you a little better. I'm not sure I feel this is a con anymore, but I thought I should address it. Maybe I should have labeled this section "quirks"
- the toe is coming slightly unglued, but it's not bad, so far.
- Another quirk is that when you first put them on, you kind of feel like your toes are hanging out over nothing. Almost like they're hanging over a ledge or something. It's a very weird feeling and I was a little worried about how that would be while running when I first tried them on, but it was not noticeable at all once running. Over time the little bit of padding they do have wears down (or possibly I just got used to the feeling) and I'm not sure this ledge is even there anymore.
- These shoes have a lot more to them than vibrams. If you're new to barefoot/minimalist running, definitely try it completely SHOELESS a few times to make sure you have a reasonable stride before running in these shoes. It's a little bit shocking, the difference between completely bare and these shoes. Still very minimalist, zero drop, you can curl them right up in a spiral, but NOT barefoot.
Overall, I obviously like them a lot. I definitely would buy them again, but I think I'm going to use them mostly for trails from now on. If you run mostly on asphalt, this shoe may not be for you.
