I have been an Asics guy my whole life. Back in high school, I wore the GT-2020s and even bought multiple pairs of them because they easily lasted over 500+ miles each. I was a customer for life and bought 2030s, 2040s, 2060s, etc. all the way up to 2170s. My 2170s are on their last legs and I was sad to learn that the line has been discontinued. The GT-2000/3000 is supposedly the successor, but I tried both of them and they feel nothing like the Asics I've loved all of my life. I can't even find the 2170s or anything below online anymore. I wish I bought 20 pairs of them before they were discontinued.
Now I play basketball more than I run. My favorite basketball shoe of all time are the 2013 Hyperdunks. I don't like the 2014 even though it got similar reviews, and they completely ruined the line with the 2015 version. I'm thinking of buying 10+ pairs of the 2013 online before they are all gone, and hopefully these will last the rest of my life. There's some fancy materials in this shoe like Lunarlon cushioning, dynamic flywire, fuse material, etc. If they are stored in a closet unused, will I be able to wear them say 20-30 years from now? Assuming I am still alive and in good health.
