Id highly recommend this product. Wearing Crocs with socks is like wearing sandals with socks, wont do it, but the lining keeps my feet nice and warm! I probably doesnt matter where you buy them. Then no warning they?ll just power off suddenly, saying the battery is too low. I do also look forward to using it with a small group of people for audio conferencing when back in the office as it will give some additional flexibility in breakout areas. I also finagle it onto my bike rack, on the back of the car, for traveling. I do love this sandal, however the seam that goes across the top of my big toe is so very very uncomfortable. these are great shoes nice on your feet and not heavy very easy to walk around in. The north face have excelled themselves. She said it was like walking on marshmallows, pillows, clouds, ( insert other soft things here).
