Do you have any sporting goods or work clothes stores nearby? Try the yellow pages and make some calls.

L.L. Bean is good about returns if you order online from them.

Adams carries them in the spring. I saw them at Kenco Sporting Goods on Rt. 28 in Kingston today.

If you are in Tarrytown (I am in Cold Spring in Putnam) I would call around to places that sell equestrian supplies, since muck boots are an essential for cleaning out horse stalls. Bedford area, let's say?

I tried them on at Adams - the muck shoes fit fine but I can't get the boots on which is what I had suspected all along. But the shoes are great in this kind of weather.
