OPEDIX CORE-Tec Compression Shorts Review

The OPEDIX CORE-Tec Short is similar to the CW-X products where they claim to have targeted compression. When I first saw the CORE-TEC short they looked a lot like the CW-X compression shorts I have used in the past. “CORE-Tec™ Shorts have scientifically designed tensioning systems built within a comfortable, form-fitting base layer to enhance the kinetic functioning of your body. Working like an external muscle, a combination of fabric tensions help direct the body’s internal forces and optimize harmonious joint function in the body’s kinetic chain.”

The Fit

The biggest difference between the CORE-Tec shorts and any other short I have worn for running is how high they come up. The top of the shorts come up right under the belly button. This is intentional to give support to the abdomen. At first I was not comfortable with how high the shorts come up. Every run I went on with the shorts I had to get used to the girdle feeling. Later in the runs it became less noticeable, and on an 18 mile run I felt the benefit from the compression on my lower core. I like to run without a shirt, but the high waist would make me a little shy to run shirtless in these shorts. The fabric that covers my “cough” junk left little to the imagination. The length of the shorts is spot on. They are not too short or too long. They ended up being about 4″ above the knee. Another nice feature is there is a band of sticky rubber around the cuffs of the leg openings that hold the short from bunching up. I wear mediums in all my shorts and the medium CORE-Tec fits great.


These are well made shorts. The quality of the materials used shines through. They feel better against the skin than the CW-x. I have to wear a base layer under the CW-x because the seam that runs down the crotch rubs. The first thing I looked for in the CORE-Tec was that seam. I was happy to see they covered the seem with a friendly looking piece of material that doesn’t seem to add bulk. The stitching is solid and I have seen no pulls or abration spots on the fabrics.


I have worn the CORE-Tec shorts on runs as long as 18 miles and as short as 7 miles. The benefit of the targeted compression was felt more on the longer run than the middle distance runs. I will consider wearing the CORE-Tec for my next marathon or ultra. With compression shorts you don’t have to worry about chaffing, so even if you are not looking for the target compression avoiding the chaff makes wearing compression shorts in humid conditions worth trying. OPEDIX CORE-Tec short is a quality garment, I recommend giving it a try especially if you like CW-x and compression garments.

  1. The downfall of my CW-X Stabylx tights was the crotch seam. I actually wore through the thread in that seam. Have you worn these tights long enough to notice an increase in durability when compared to the CW-x?

  2. Jonathan says:

    I’m interested to know how durable the seams are in these shorts. I wore through the stitches in a pair of CW-Ws and am wondering if these will hold up better. Can you let me know how these did for you?

    1. The Opedix are holding up well. They seem a little higher quality than the CW-X.
