I would not recommend to use these as your everyday shoe unless your feet are used to a very thin sole with no support. The grey hat in my photos is the 6277, the green is their 6377. Bumped down one star because I paid extra for delivery and it arrived one day later than expected. Some folks commented on the weight, Im not noticing any real heaviness. It wont take long before these get lost. La calidad de sonido es buena. They also support my calves stopping RLS at night! This case was a bit pricey, but its from a reputable company so I thought Id give it a try after buying some cheap silicone case that did not even close. The shoes is pretty and I like how it looks. these fit like normal running/tennis/athletic shoes, and were about half the price of many of the other options.
