The HRC sock from Giro comes up to roughly the calf belly, which is ideal for my style. The fabric Giro chose breathes extremely well, and I often find myself looking down to see if the shaft has fallen because it feels so breezy, and thankfully, it never moves. I purchased the grey sock for its ability to remain new-ish looking after a proper day in the dirt. I've logged about 20 rides so far using the HRC and there are no signs of loose elastic bands or stretching. Love the sock.

Comfortable and good looking! Great summertime sock!

Good ventilation, cool colors, and a nice cut make for a great sock!

I have one in every color, they are compression type socks, my shoe size is 7-8 womens and the small fit very well, my feet are not sore after long rides

Best bike socks out there. They're durable, don't smell, come in great colors.

Lightweight, comfortable and breathable. The fit is true to size and the colors are on point. These are my new favorite riding socks!

My favorites. I save these for my weekend rides. Lightweight, breathable and supportive but more importantly, the perfect length to show everyone that you are a discerning cyclist able to dope when ever you want to. These socks are so comfortable!

Like really! At the moment, these are my favorite socks; checking every single box a box checking cyclist like myself could ever desire. -They fit uniformly across my size 44, slightly wide foot. Other socks I've worn in the past have bunched up in some areas, and stretched in others; something the HRCs never did.
-They have enough material to feel supportive, without feeling constrictive, or losing the ability to ventilate.
-They are cut to the absolute ideal length. Stopping just below your calf begins. (Short socks=bad. Don't do it.)
-You'll pretend you don't care, but the blue color will jive SO nicely with your blue Giro (or otherwise) helmet.

Go ahead. Pull the trigger.

Nice light, tight fitting socks.

They fit fine. Quality is OK. They're socks. There's nothing to go crazy over.

You can never have enough socks. I prefer black because it won't show dirt stains like white or lighter colors will. You can hardly tell that you have these suckers on.

I actually like these socks! They are super lightweight and breathable. They are also just tight enough to stay in place and never slide down.

My only complaint is that they run a little shorter than I would like. I have always liked a little but of a taller sock and these are just a few inches too short. Other than that I have no complaints!

Not sure about the rest of you but I always have trouble finding socks that "fit" and have the wicking performance I need. Living in Texas my feet tend to sweat more than normal and these socks really do a good job of wicking the sweat and drying out, something that I usually only found in other "euro" brands that always seemed a size to small and were a struggle to get on. These socks are "goldilocks"; not too tight, but not loose either...and they breathe!!! Get a pair or 4...seriously!

Nice snug fit and they feel really light. No complaints.

I really like the Giro brand for socks and bike hats. These socks are real durable and light weight. Perfect for my cycling and trail running.

The light weight and durability make this one of my favorite socks out right now. Sizing is true, but keep in mind that these are supposed to feet like compression socks.

Medium to thin sock perfect for summer. Just the right amount of compression on the foot and ankle. Have used them twice and don't even notice they're on - that's how socks should feel. My foot size is 11 US. Large fits perfect.
