Why Was ShockSorb Made? - Understanding the ShockSorb.


The two most common questions I get are: "How and why was the ShockSorb made?" This article will give more insight into the development, testing and marketing processes.


The story of the ShockSorb dampeners cannot be told properly without a little personal background. My family moved to the United States from South Korea when I was 8 years old, to further my dream of becoming a professional tennis player. I worked my way up to the top five juniors within each age division before having the honor of being hand-picked by Nick Bolletieri to attend at IMG Academies. During my time at IMG, I had the chance to train with the likes of Serena and Venus Williams, Tommy Haas, and many other top tennis players in the early-mid 2000’s.


My time at IMG included some of my toughest training and most intense matches. While I was no stranger to intense workouts and training sessions, one opponent that I could not seem to conquer was my chronic shoulder pain. As I continued playing and training, my shoulder pain worsened into something that put me out for over a year when I was at my peak professional ranking.


After my professional tennis career, I found a new passion in coaching professional and recreational players. This has been (one of) my occupations during the last decade and had countless chances to test various racquet, string and tension combinations for myself.


After testing different racquets and string combinations (2-3 days) my shoulder would always regress into the same pain that I would battle while on tour. I was comfortable with my body and understanding its needs, knowing this pain wasn't immediately an injury. Had I continued to play test other racquets/strings long enough, however, even just 2-3 days, my shoulder felt like the rotator cuff was starting to tear. The weird thing to me was that I had never changed my technique - the only change was the racquet or strings.


After realizing that it was not my technique or overuse, I theorized that the problem stemmed from the different vibration frequencies when I would test the various racquets and strings. My main/preferred racquet setup would not hurt my shoulder whatsoever. In light of this, I wanted to see if using a better quality racquet dampener would help with my shoulder pain.


Naturally, the first thing I did was search for the best dampener on the internet. Ne
