First of all Sorry if I double posting the same thread anywhere . Just curious how long would these be wearable for? My wife's True Blue 3 2016 is still wearable despite the yellowing of the rubber front toe area. I was thinking of starting a collection of 3's, so is that a good idea? I'm in Malaysia by the way climate here is very humid here so everyday at night I will switch on the AC and it will auto switch off by 03.00 hours. I would love to hear some feedback on 3's lovers out there peace
