Okay. Now that I have a few minutes and access to my laptop (I blogged that picture of the socks from my phone) I can give a real review.
I had bought one of the lower end Feetures socks to wear for the Chicagoland Half Marathon, and they were great. I liked them so much (prevented blisters, wicked away sweat, etc), that I went to my local running store and bought some more. What I didn't pay attention to were the type. They were the same brand, but cool colors. Yes, I got distracted by the colors. The new ones I bought are Feetures Elite!
What's different? A lot (besides the colors). The elite version is more like a compression sock especially around the arch. They also are nice and thin, which works well for me. My feet swell like there's no tomorrow when I run. I've run a few times with the new socks, and so far I have no skin issues (blisters, sore spots, etc). I also have fewer issues in general with my feet. Talk about a good mistake to make!
The only downside is for those who are trying to be cost conscious. I bought four more pairs of socks today and spent over $50. With a discount. The lower end Feetures do cost less. The compression feels really good though, so I'm going to invest in a few more pairs. I have enough for six days of running which is one week's worth. Whether you get them is up to you, but I'm at a point in my running where it makes sense to invest in these kinds of details. My feet ended up looking horrible from all the blisters and callouses from the last training cycle, and I think these socks will help minimize that.
