KEENWomen's Clearwater CNX Sandal

Q: Others said the non-adjustible strap is too tight at first fitting. Does it loosen up?

Yes, they are too tight! My husband cut the straps so I can keep them. Way too cute to return! Keen, very disappointed with this glitch, but they are adorable!

Q: Do these shoes have any arch support? I have high arches so I am looking for arch support.

I have high arches and use these sandals often in the past 3 years. Last month on vacations i lived in them. Walked roughly 20,000 steps daily - no issues whatsoever. Fabulous!

Q: Are these non marking soles. Want to know if they can be worn on a boat without leaving black marks.

I don't know about a boat, but I tried to make marks on a number of wood surfaces...painted and stained. There was never a mark when I rubbed many parts of the sole on the surfaces.

Q: Are these comfortable without socks?

super comfortable without socks, IF you get a pair that's constructed property...they have a big quality control problem--i bought one pair that is fabulous, but the next 2 pairs had to be returned because the neoprene toe cover was too short, and it grabbed at my toenails.
