I'm coming up short on this one. There is absolutely no official release with subtitles, though Toho did release them on Region 2 DVD without subs.
As for boots, we don't advertise such here, but I suppose it's okay to say I can't find much in the way of fansubs--Though admittedly I wasn't looking too hard in that area. Zone Fighter's largely the same way.

Hey, sorry for the late reply. I recently heard of these and found this post in my search. So far all I can find is a release on amazon that appears to only have one episode of each. It says it has subtitles. https://www.amazon.com/Greenman-Godman-Japanese-Language-Subtitles/dp/B01H517YI2/ref=sr_1_1?ie=UTF8&qid=1508891674&sr=8-1&keywords=greenman+godman
There's an ebay listing for the region 2 release, though sadly I can't justify that big of a purchase (85.99+7s) on nonsubbed shows that I don't even know if I'll enjoy. If you find anything let me know!
