GEAR REVIEW – OS1st Performance Socks
My distance running and the copious miles leading up to an effort take a beating on my socks. I’ve spent decades with foot issues and found that a lot of them revolve around failing to choose the right sock for the right activity.
I’ve tried every fad sock out there, from toe socks to crew vs. non-crew to compression style socks. It turns out, my preferences shift from road running to trail running to mountain running AND that is ok.
Recently, I was presented the opportunity to test out OS1st socks. I’ve heard some mention of these socks in the sector of the ultra running community that’s not obsessed on over hyped toe socks (those serve a place too, but I’ve had horrible luck with durability).
For purposes of this review, I received a pair of FS4+, FS4, and TA4 socks. For sizing, I am a Women’s size 10 shoe size (EU 42). Here is a run down on three socks I tested in the OS1st line-up and the conditions I found they excelled most:
- FS4+ Compression Bracing Socks – Over the Calf
- FS4 Plantar Fasciitis Compression Socks – No Show
- TA4 Thin Air Performance Socks – No Show
FS4+ Compression Bracing Socks – Over the Calf ($49.99)
Product Tested: FS4+ Fusion Pink, Size M
Since that run, they have accompanied me for every big day in the mountains. I love the firm compression around my arch that makes my nagging Plantar Fasciitis seemingly disappear while wearing them. These run true to size, if not a tad large; however, once they are on there is ZERO slipping down my leg regardless of how many hours or days I wear them for. The reflective details are an incredible touch, as many of my runs extend through the night and I appreciate the extra visibility. As for durability, none of my toes popped through the socks and they survived a few washings so that’s a great sign. I’ve only had these for a month, so I can’t speak to their long term durability just yet.
Ideal Use: Long, strenuous efforts, recovery or jobs that require standing on your feet all day
FS4 Plantar Fasciitis Compression Socks ($24.99)
Product Tested: FS4 Merino Wool No Show Socks, Size M
This sock is available in a no show, 1/4 crew and crew. I tend to only wear no-shows for road running and dreadmill sessions, but the 1/4 crew is a staple in my trail and mountain running quiver. Either way, the merino wool does an incredible job with wicking moisture away from my foot even on the dreadmill! I’m absolutely obsessed with this sock. As for durability, they seem to be holding up really well.
Ideal Use: Everyday trail running and multi-day adventures
TA4 Thin Air Performance Socks ($12.99)
Product Tested: TA4 Thin Air Performance Socks in Lavendar, Size M
Where this sock really shines is its ability to stay put, which in turn reduces the opportunity for hot spots or blisters to develop. I learned to love the right thin sock for skimo racing, which has guided me into exploring this for running as well. True in all heat generating speed sports – skimo, running, etc., thin is the way to go when friction is the enemy. As for durability, I have taken this sock out for many opportunities to implode, but it’s still functioning and intact just as it was straight out of the packaging. For a road marathon distance or shorter, this is my sock of choice.
This thin air, max air flow technology is also available in a compression calf sleeve, although was not tested by us.
Ideal Use: Warm weather activities, daily driver speed demon.
