Phenomenal customer service. Had an issue with the product, had such a good experience getting help that I immediately purchased more from Courier. Also, these things are COZY. Got them to serve primarily as cycling socks, the padding is substantial without being so bulky that the fit in shoes gets affected. Stellar compressive quality and fit.

HiFi - a masterclass in design and performance

Being an avid hobby jogger, I have spent way too much money on socks over the years, trying to find that perfect balance of comfort, breathability, compression and cushion.
I also happen to suffer from Morton's Neuroma which may also help explain my overstocked sock drawer.
Whilst the LoFi sock is my long run hack and my go to for grinding out the miles during marathon training, the HiFi is my marathon race companion.
The HiFi sock makes my carbon plated race shoes actually feel comfortable, eliminating lace bite and increasing forefoot comfort in my Adidas Adizero Adios Pro 3, which is no small feat!
I have been most impressed by the targeted cushion areas which provides comfort whilst maximising that race day breathability I need.
And last but not least, the durability of the Courier socks, both LoFi and HiFi are miles ahead of the competition, withstanding hundreds of km's of punishment with no sign of wear.
In some of the competing premium running sock brands I own, I have usually noticed some thinning around the forefoot and heel, usually punctuated with a small hole at the tip of the sock where my big toe hits as I run.
I see no signs of that in both my HiFi and LoFi pairs.
As a result, I have just ordered a couple more pairs, can't say much more than that!
