Byron D.wrote a review of Trigger Point TP Massage Ball on March 9, 2017
Familiarity: I've put it through the wringer
I had a bout of plantar fasciitis a few years back and bought one of these to roll out my feet. It was recommended by my physical therapist. Flash forward to now and I still keep one under my desk at work and one at home. I roll my feet on them after I ride and they help keep my feet really nice and loose. With loose feet I've noticed less stiffness in my calves, upper legs and lower back as well. If you keep your feet happy, your whole body just stays in better form/alignment.
The ridge on this ball is the key. It works better than a lacrosse ball because the ridge can dig into very specific areas. I also use a tennis ball occasionally to warm up my feet for a go on the more intense TP ball. The soft nature of the tennis ball helps get the blood flowing in the foot and provides a gentle overall massage before the real work begins.
I know this ball appears relatively expensive, but it is worth the price.
