Those wishing to try Zem booties may be glad to know that about a week following my earlier post, a call came from Steptuit, followed by the booties, which arrived today.
They weigh 4.9 oz, compared to 3.9 oz for my Deep See ankle height dive sox with textured soles. However, they have a much more rigid sole, more comfortable to wear in camp, with projections that are not cleats, but will grip much better than the textured sole. Their only drawbacks, by comparison, are that the dive sox are about 1.5" higher at the ankle and made of much thicker neoprene. Conclusion: The Zems are probably better for camp wear over sox or thinsulate booties; the Deep Sees are probably better for very cold weather, or very cold streams during fording. Both fold to about the same size. Am leaning toward the Zems, for trekking in the summer anyway.
The Steptuit proprietor was most apologetic, and it appears, did receive my email inquiry about the order, even though it was returned with a message stating the address was invalid. Those more schooled in IT may understand how such things occur. Glad they eventually got back to me and filled the order.
Thanks to Ken Larson for posting the info about Steptuit.
