Gear Review: CEP The Run 4.0 Compression Socks & Sleeves

A group of runners wearing CEP socks.

The Run 4.0 is CEP’s latest collection of compression socks and sleeves geared towards athletes seeking an edge in performance and recovery.

Whether you’re aiming for new PR or you just want to experience the benefits of compression, The Run 4.0 socks and sleeves will help you feel your best. Plus, fresh new color options allow you to customize your style. These socks and sleeves can be worn during runs to fight fatigue, after workouts to aid recovery or while traveling to increase circulation (no one likes swollen feet after a flight!).

Medical-grade compression tells us CEP means business. Their higher quality compression improves blood flow from your legs throughout your body, flushing out lactic acid, while lightweight mesh materials give you room to breathe. CEP compression socks and sleeves also use graduated compression, meaning they’re tightest around your ankle and gradually loosen up towards your calf.

Fleet Feet reviewers tested The Run 4.0 compression socks and sleeves to see how they fared during long runs and everyday wear. Here’s what you can expect from CEP’s latest collection.

The Run Compression Tall Socks 4.0

CEP’s Run Tall Compression Socks 4.0 are the same classic style as the best-selling 3.0 Tall Compression Socks, with a few notable upgrades. The material used in the 4.0 socks are lighter and more breathable, making them even more comfortable for sweaty runs and workouts.

“These socks are super comfortable. I wasn’t sure how such a thin material could provide so much compression and support, but it somehow works! The new material will be a big hit with anyone who wants the benefits of compression but felt the 3.0 socks were too thick,” says one reviewer.

A redefined compression profile allows for precise, targeted compression in your feet and calves, allowing you to recover quickly. Wearing the socks before, during or after activity will also help reduce inflammation and swelling.

“I wore these for a few hours after a run during which my calves had been very sore and tight. They felt noticeably better afterwards,” says one reviewer.

A padded footbed in the forefoot and heel increase comfortability while reducing blisters and chafing.

If you’re craving the full benefits and complete support of compression, the Tall Socks are the best option in The Run 4.0 lineup.

If you’ve ever suffered from calf pain or shin splints, the Run Compression Calf Sleeves 4.0 might be your jam.

Supportive medical-grade compression extends from your ankles through your calves, and just like the sock counterparts, improve circulation and eliminate fatigue. It’s best to wear compression calf sleeves during activity to prevent blood from pooling in your feet.

“The compression sleeves give me confidence for long, hard efforts, and my legs always seem to bounce back a little faster after I use them,” says one reviewer.

The Run Compression Calf Sleeves 4.0 use innovative technology that keep you cool in warm weather and warm in cool weather. Plus, you can wear virtually any type of sock with the sleeves.

“These sleeves are really comfortable to race in, and I like that they regulate temperature. I can wear them with shorts whether it’s a cold or hot day and they always seem to feel good,” one reviewer says.

If you want targeted compression specifically for your calves and shins, or you’re picky about your socks, the Run Compression Calf Sleeves 4.0 are a great way to maximize your performance.

The Run Compression Mid Cut Socks 4.0 are the upgraded version of CEP’s 3.0 Short Socks, offering graduated compression in a slim, athletic cut.

Runners, walkers and fitness enthusiasts will appreciate the light, breathable material and versatile design. Moisture-wicking fabric helps keep you comfortable and dry, no matter the weather.

“They feel nice and snug––but not tight or restrictive––on my ankles and lower calf, near my achilles. They stay in place without any bunching or shifting around. They’re very comfortable on the run,” one reviewer says.

Targeted compression supports your ankles and arches, so you can feel fresher and less fatigued during runs and workouts. Extra padding in the toes and heels provide shock absorption and help prevent blisters.

“I’ve worn them for medium and long effort runs and have had zero problems with blisters or any kind of discomfort. I’ve totally forgotten I’m wearing them on the run, which is a good thing,” says one reviewer. “The support that they offer is subtle and distraction-free.”

If you want breathable compression for your feet and ankles without full calf coverage, the Mid Cut Socks 4.0 are the best choice.
