Description
The Aspire Four Sock is the perfect 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.

Reviews
Asked for and received as a gift. Not too thin, not to thick, not too high, not too low. Most comfortable bicycle socks I have ever worn, in many many years of riding. I have worn them on every ride since I got them, in rain, heat, and on the trainer. Had never heard of the company before, but if the one pair I currently have is the norm, I have no reason to look anywhere else for bicycle socks again. I will be buying more of these, and looking at the company for colder weather sock options as well.
The blue pair I own are gorgeous, but agree with another post that some more aggressive bright color options would be welcomed.
I love these compression socks. They are very comfortable on long rides. As another reviewer mentioned they seem to hold up very well after many washes. I would love WBW to offer more crazy color options as socks make the kit.
I bought these colorful socks (pairs of red and flourescent yellow) mostly for visibility. Turns out they are super comfy too, not ultra thin traditional cycling socks, just a bit more plush. And with a 4 in cuff they offer enough visibility as a moving color patch to be effectively seen by drivers without being tennis-sock tall.
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.
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.
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.
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.
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.
