I am a fitness trainer and use the soft rollers for my SMR (Self Miofascial Release) Workshops. The soft rollers are not harsh to use for those first experiencing the wonders of foam rolling. Also, the soft rollers may not cause as much pain when rolling over trigger points, allowing the beginner to get acquainted with the sensory feedback created. Also, when laying on the soft foam roller lenthwise for balance or aligned spine exercises, it compresses a little more giving a slightly more stable surface. As I am an avid promoter of foam rolling, I hope this review has helped.
