Long-time lurker here.
It appears Ovation has bought them out.
Here is a link to much cheaper Dafna’s

FWIW, I bought a pair of these off ebay in 2001(?) and I still have them. They are different than the ones I bought winter before last: Old ones denser / heavier foot construction with removable WOOL liners. New ones - well the reflective stripe is painted on, and started wearing off 1st season. Synthetic fleece-lined, which I don’t care for as much as wool. I would recommend getting a half or full size larger and wearing THICK, heavy wool sox if need feet warm, as constriction is 1 reason for cold feet.
I have no clue on the Ovation brand, but I’d still recommend these at this price. These are also great for wading thru snowdrifts - I even bought my husband a pair. I wear mine ALL winter: mud, snow, ice, riding, etc. It is truly AMAZING how good the 12+ yo pair still look - wish they were still made to those specs!
