i appreciate your having gone more "green" but the socks don't fit as well/stay up as well as they used to. The anti-blister ability is why I have been running in Wrightsocks for two decades, but i will be looking around given the high cost and lower quality.
Had an issue with one sock, they replaced it without question.
Somehow, the lined Wright socks are different. I’ve worn them for years but this batch is sagging into my shoes when I wear them. The ones I purchased last year did the same and I threw them away. I thought I’d try it one more time and ordered 4 more. Unwearable.
Hi Stasia,
We're sorry to hear the Running II didn't perform as well as you were expecting. While the Running II does tend to fit a tad looser due to it's placement of its Lycra, they should not sag down into your shoes. The most typical reason for this is usually the socks being to large or loose fitting shoes. If you have any questions or concerns please reach out to our email cs1@wrightsock.com or give us a call at 800-654-7191 and we will assist you however we can. Thank you for taking the time to leave a review.

Please, please don’t “redesign” your remarkable socks. I’ve been running for decades using the low-cut double-layer anti-blister system as my under-socks with Thorlo Work (crew socks) as a top layer. No blisters, no problems, many pairs in reserve . . .
I never hike in any socks other than Wright. I have several pairs of different types. I've worn Wright socks on the Camino de Santiago, twice, and again in May this year. That totals about 1000 miles. Wright socks got me through that.
