I received a pair of these socks from the Rockleigh 105 gravel ride. After a few weeks I found myself looking for these, rather than others, to wear for a ride or for work.
Comfortable as, so I bought a few more pair to wear for work too.
I love the mullet trail socks. I wore them for the first time completing a slow 14 km trail run through 11 creek crossings. The socks quickly wicked away the water and worked in synergy with my trail sneakers, leaving my feet comfortable and cool for the duration of the run and the commute home.
These new trail socks are great for running the Tassie trails. Good looking and super comfortable.
I have A LOT of socks and these are now my favorite winter cycling sock!
I’ve worn these cycling in the cold and they don’t only look pretty rad, they also keep your footsies toasty warm
I also wanted to use them trail running but for that I prefer a tighter fit. I wear a size 40 shoe and I will go for a size small for my next pair instead of medium.
I did nevertheless use them for some hiking in Austria. I thought I’d only wear them for half a day as it was quite warm, but my feet did not feel too hot by midday so I left them on. My feet had no problems whatsoever, so I know they will be awesome for trail running as well. I really would love a mid-length sock like that!
New Mullet socks are the most comfortable trail socks I have found. Heaps of padding for the long trails keeping the feet nice and toasty on the winter runs. The ankle cover is perfect to stop all kinds of stuff getting into the shoes. My new go to socks for trail runs. Awesome stuff from IoMerino
Bliss for the feet. Reluctant to wear these out on the trails as they make such comfy van/house socks but I know with being wool they will stand the test of time. Wore them in a crucial part of a long run where there was multiple wet feet stream crossing followed by steep and rocky terrain and these beauties kept my feet warm and in great condition. Ladies probably best to size down for a more firmer fit.

read more review here “ I can honestly say your products are at least 25% better than (that other brand). And I’m a Kiwi. Not to mentioned feeling better about Fiji production and the fact that your cuts fit me better. The weaves are also finer and feel softer. Good on you and please share this with your team. I love supporting you! Heaps good.”
Find out more While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability.
It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.
