I've been wearing adrenalines for a long time now - probably over 30 pairs - and have been very happy with them, but with the last two updates I've felt like they wear out really fast. I heard there were some complaints about this with the 6s, so they switched to the MoGo foam, but even with the 7s I feel like the wear out really quickly. Around 250-300 miles and they feel really shot to me, whereas with my older adrenalines I felt like I could get 400 at least. Has anyone else noticed this? It could be I'm being paranoid because I'm coming back from a bad injury. Thanks.
