For those of you who are longstanding readers of iRunFar’s gear reviews or who spend time with me on the trail, you know that I’ve been wearing compression garments for about the last three years. I know and love that, for me, compression wear in general provides a bit of biomechanical support, reduces the vibrations of soft tissues in the lower half of my body from impacting the ground, and reduces fluid retention after long runs and races, as well as during long travel outings. So, when the chance to test the Opedix CORE-Tec Short ($165) came my way, I didn’t hesitate. Three months later, I’m still totally stoked on this short.
What Opedix Claims the CORE-Tec Short Does
When claiming that the Opedix CORE-Tec Short helps users maintain core stability, Opedix leans on a study recently done by researchers at the University of Denver’s Human Dynamics Laboratory on pelvic stability and proprioception. In the study, a very small number of subjects were asked to do a couple sitting and landing-based tasks both while wearing and not wearing the CORE-Tec short. The studies concluded that, while wearing the short, the subjects had significantly more stability and prioproception doing these (non-running and non-skiing/snowboarding-related) activities.
Fit and Performance
I dig these shorts because I believe they help me with a couple minor biomechanical hitches in my giddy-up. When my body grows tired during a long run or race, my pelvis tends to start tilting anterior-ly, just a little. I haven’t been tested by a PT to determine which muscle groups are the cause of this, but my guess based upon what I’m feeling on the run is that my deep, lower abdominals fatigue earlier than other muscles, leading to this tilt. And, for as long as I can remember, my left glute medius has never quite been as strong as the right (even though I work on its strength and mobility). When I get tired, I can feel torsion develop in my pelvis as other muscles start firing on the left side to “cover” the left glute medius’ slacking behavior. In testing the CORE-Tec short, I’ve found that I can consciously keep my lower abdominals active for longer before they fatigue. And, I haven’t encountered a run yet where my pelvis starts to lapse into torsion due to glue medius misbehavior. That is, the shorts seem to bear enough of the stability burden that I can maintain good mechanics for longer.
I would encourage to Opedix to develop a hot-weather/lightweight design. They are pretty thick and decently heavy for a pair of compression shorts. Temperatures hit the high 80’s Fahrenheit during testing, which is decently hot, but I can imagine they might wear really warm in temps even higher. Also, I’d love to see some sort of tiny storage pocket on the short, something in which you could store chapsitck, empty gel wrappers, salt, or something similar. I imagine it is a challenge to create a pocket that doesn’t affect the function of the panels, but I bet these folks can do it!
I really like the short. It’s been a mainstay of my summer running/racing/fastpacking wardrobe. I’d love to see Opedix further substantiate the claims they make about what the short does with some larger scale studies of subjects doing the activities the garments are advertised to assist/enhance. But, anecdotally, I like the way the short fits and functions on my body and plan to keep using the short. Also the price is high, but I get why; it’s a tiny company creating a tech-y product that has to be expensive to do on the small scale on which they are currently operating. Big props to Opedix for taking the functionality of compression garments another step forward.
