I know that there was a lightweight trainer introduced on the Japanese market known as the LunarSpider LT (the LT standing for lightweight trainer). I have seen some pictures of that shoe, as well as the recent US shoe debuting here as the LunarSpeed Lite. The outsoles appear the same, and the upper has some very different colorways but looks mostly (though not exactly) the same. Does anyone with some experience with both shoes care to comment? Are they the same shoe with just a different release name, or are they two separate shoes?
