I bought this because I do yoga. Whenever I work out a bit of sweat, my feet are the first to get sweaty and begin to slip on my yoga mat, especially during chaturanga dandasana, downward dog, and when holding poses like warrior 1 and 2.

I am generally happy with this pair of socks - the traction is good. It is the perfect size for me; fits just right. HOWEVER, there's a problem: the socks doesn't entirely stick to my feet - it moves around slightly - especially during the time when I jump backwards or forwards for chaturanga dandasana. As a result, I had to adjust it from time to time, lest it slips off from my feet due to my jumping movements.

So if you are doing Ashtanga vinyasa or more vigorous sort of yoga, be aware of this problem. If you are doing a slower kind of movement exercise, then I assume it should be alright. Again, the traction itself it okay; it's the looseness during movement that bugs me (and yet a smaller size wouldn't work for me because this size fits perfectly for the length of my feet). So watch out for that!

It would get 5 stars if it's tighter, and hence sticks to my feet better. Oh well.

There's another problem which can't be blamed on the design of this socks, but still, yogis out there, you should know that many yoga sequences are structured in such a way that you'd move from sun salutations (when wearing TractionSocks might bugs you a little due to the reason stated above), to standing poses (when wearing TractionSocks is a really good idea), to sitting poses (when you probably have to take off the socks), and finally, to resting/relaxation (when wearing TractionSocks is nice because it warms up your feet). I find the wearing, taking off, and wearing socks a bit tedious. Not the socks' fault but still, yogis out there, you might want to bear that in mind.
