I bought the Zems just in
I bought the Zems just in time for the cold weekend, and used them in a 5k race today. Love 'em!
I ran 4.5 miles to the race in the Zems. It was around 25 degrees and dry; feet stayed nice and warm. I had hoped to run the race barefoot, but at race time the temp was still in the 20's so I kept the Zems on for the race. Besides, my feet had cooled off a bit while I was standing around waiting for the race to start. Then, after getting my ribbon for finishing 3rd in my age group (I'm not that fast; it's a small town race), I ran back home in the Zems.
When I got home my 8 year old said, "Hey, Dad, I want to run a mile. Will you run with me?" So I ran another mile with him - glad to do anything to encourage my boys to run!
The Zems are very flexible and allowed my feet to flex, stretch and splay in any direction. They're minimal enought to give some feel of the ground. Although I couldn't really feel the textures of the roads/sidewalks, I could feel cracks and pebbles, etc. The sole seems to be made of a durable hard plastic. It's not a soft plastic, so even though I'm nearly silent barefoot, the Zem made a bit of a slapping sound on foot strikes. They allowed good air-flow, but protected my feet from the cold air enought to keep my feet warm, as long as I was moving. They are NOT water proof, at all. There was some frost/snow on a board walk, which was part of the race, and the Zems got wet quickly from that, but it wasn't enough to make my feet cold. However, I'm doubting that I'll enjoy wearing them in cold wet conditions. All-in-all I'm really happy with them, and glad to have something to wear in cold, albeit dry weather.
