I wore Lunareclipse and later moved to Lunarglide. Once I got between 300 to 350 miles on them the midsole (EVA I assume) foam was shot. The shoes would cause either leg pain or foot pain during runs. Switching to a new pair would eliminate the pain. I agree the Lunarglide were very comfortable for casual wear and with any socks due to roomy toe box. The prior Lunareclipse were not as roomy. I still wear an old pair of older Lunareclipse for casual wear and still have an unworn pair or two in boxes I have yet to rotate into my running shoes. I never bought that more recent Lunarglides as I did not like that changes Nike made to them. I switched to Adidas Supernova which I got 1000, and 915 miles out of until the outer sole wore through. I now wear Adidas Boston (600 mile thus far) and Adidas Solar Glides. The Supernova and Solar Glide are just as comfortable as the Lunarglides were for casual wear with various socks.
I run 30 to 50-some miles every week. I weigh 165 to 170 lbs.
I too bought Boston 8 for $32 from Adidas eBay store last fall. My wife and daughter do not like the color as it looks pink in the right lighting. I have actually gotten some compliments from others which I have not received for other shoes that look more normal. I bought 6 pairs. I could not pass up the price. I have a pair of Boston 6 with nearly 600 miles. I think I can get 700 to 800 miles out of them before the Continental outer sole will wear through to the midsole
The Adios 4 also went for about $45. I bought one pair to try. Solar Glides were as cheap as about $45 from the Adidas eBay store late last year. I love the low prices we can buy these Adidas shoes for and stock up on several pairs when they go low. The Adidas eBay store has had some of the lowest prices. I have gotten some good prices from a local Adidas Outlet store. I probably have gotten some good deals from their website but not recently.
The midsoles of the Nike I wore for years wore out before the outer soles. This occurred around 300 to 350 miles. My Adidas shoes with Boost midsole have worn out in the outer sole at 915 to 1000 miles while the midsole, while a little firmer than new, still had good cushion.
My Adidas shoes wear out in the same locations in the outer sole.
