Description

The Aspire Four Sock is the prefect sock for the serious cyclist.

Swiftwick bills this as the most technologically advanced sock on the market, and while we might not be able to speak to that, they are pretty fantastic socks. Thin and lightweight, the Aspire is perfect for use under snug cycling shoes (or running shoes if that's more your thing) and the level of compression over the foot, ankle, and Achilles tendon aids performance and recovery. Another unique quality of these socks is their lack of a toe seam using linked-toe technology, which eliminates bunching and improves comfort. As with Swiftwick's other socks, the Aspire's durability, breathability, and moisture wicking are also top of the line.

The Aspire Four Compression Sock features a four inch crew length cuff.

Very comfortable

I've had some original Performance Swiftwick pairs for years - they seem indestructible. These are a little thinner for warmer days, feel great. Yellow ones are great for visibility. Hopefully will also last, but haven't had them long enough.

Great feeling sock for the long ride

This sock feels as good when you put it on as when you take it off after a century ride. Feet seem to stay fresh the whole ride. Great Sock

Simply the Best

Think Tina Turner...Swiftwick socks are hands down "simply the best" cycling socks you can buy. These socks are going to last forever. Got both blue colours. Think I prefer the seven's over the 4's

Nice Support For The Achilles

I damaged my left Achilles decades ago. Whenever I ride a bike, I need to be mindful of crank speed as higher RPMs will cause my ankle to ache for hours if not days. I'm 65, for context, and I wore these and the support is amazing. I was cranking over 100 RPM and had no pain or residual discomfort at all. Amazing support.

Very comfortable but expensive.

These are great bike socks. I've been wearing them a lot. They provide very mild compression, but they are fully breathable and fit very well into my bike shoes. Only problem is they are super expensive. Look for a sale.

Run or ride these sock are awesome.

Whether Biking or Running these socks are extremely comfortable with great wicking quality, snag proof, and keep their elasticity. We put in over 5000 miles a year and the socks are still in great condition.

Comfortable and gooding, too

these are the most comfortable athletic socks I have. I use them for biking, golfing and walking. The compression makes my feet feel good while active. No more seams or excess material hanging and annoying. Colors are very visual and add to the fun.

Great cycling socks

I will now only buy Swiftwick socks after cycling for more than 30 years. They are the best.

Excellent design, quality, and fit. They do not stretch out, nice and tight, and wash perfectly well.

One thing for sure that you get Swiftwick, is total comfort in your cycling shoes.

Buy them ! You will like them too.

Great sock! Very comfy.

OK, I've never gone in for cycling socks before. I just thought they were over-priced compared to the more generic, thin, running-type socks I could buy for a lot less money at the local sporting goods store. Yes, I was wrong. WAY wrong! These are very, very comfortable. Sweat seems to dry a lot faster. They are supportive without being constrictive. And from what I can tell, they stand up to the washing machine a lot better than the mostly cotton socks I was wearing previously.

A good fit in riding shoes and a great choice of colors

I ride 6000 miles a year in cold and hot weather plus various areas of North America.

These socks handle perspiration well, don't fall down and leave room for my feet to move in my shoes while still

supported well by my riding shoe adjustments.

I bought a pair of shoes with the round dial tightness adjuster.

Best shoe investment I've made particularly if you have any foot issues.

These combined with these socks are a sure fire winner!

Best socks I own.

Best sock on the market! Just the right amount of compression and and support without being too restrictive. Keeps you dry and cool. The colors are an added plus. They also last a good while. I've had some for over a year and the compression and elasticity is still holding. They're a bit on the pricey side for socks but they're worth every penny.

It works!

It is difficult to get too excited about a pair of socks, especially in ordinary weather when you do not have to worry about keeping your feet warm. But the socks do what they say and I like the vibrant colors (in my case red). So if you do not care about matching your socks with your kit, take advantage of the cost and get these.

Consistently good

I have worn these socks for a few years as well as their merino line. They work and wear well with good wicking characteristics. They also seem true to size. My only complaint is that they are hard to find in stock, must be because they are popular, not. Bad problem to have.
