What if they are exposed to water? Are they good walking shoes?

I had to wade running water and walk through a torrential downpour to roll my car windows up in my Blair Docs, and they were fine. Dried them out with a towel and they were good as new. Of course any shoe you wear is eventually gonna get wet, unless you’re living in Death Valley or the Sahara, lol.

I made a purchase but the wrong item was sent to me, I could not make a return on Amazon, what should I do?

Why couldn’t you do a return? Call Amazon and speak to them, they are an excellent company to work with, and they will usually find a way to help you.

Can these be exchanged for a larger size?

Yes! I was able to exchange for larger size no problem.

I’m usually a size 8.5 what size should I get?

These seem to run big/large than the normal; i normally wear a size 8, with the toes out, i can wear a 7.5 in sandals, i purchased a size 8, because they didn't come in half sizes; knowing what know now, i wish i could have order a size 7.5
