text: I had a previous pair of Tevas that had served me well for years until a strap finally broke.  I couldn't find the same model, so opted for this, but also tried the Teva Terra Fi Lite.  The sole on the Terra Fi seemed clunky so I kept the Numa.  I love the soles; great support, and walking feels natural.  I had doubts about strap comfort after my first dog walk in these - the strap over the forefoot felt really rough on my foot and like there were pressure points, but it got better.  In general I'm disappointed by strap comfort - the heel strap on my right foot has been digging into my ankle bone.  But I did have similar issues with the previous pair of Tevas that ended up being great, so I'm sticking it out.  Bottom line: great soles, great for walking, straps take some getting used to (but I almost expect that from Teva at this point).  Wish they did a better job with comfort, but...  UPDATE: I ended up returning them because the heel strap wore a sore spot on my ankle.  I bought the Teva Tirra instead, and it seemed better.
