Go for a simpler and slightly softer model.
I borrowed a simpler white half-round foam roller to work out some nagging calf tightness.  It worked amazingly well, so I bought this one, thinking that the bumpy texture would only provide added benefits.  Unfortunately, this model is overall less effective than the simpler model I borrowed earlier, due to several issues.  First, this model is way too firm/stiff.  I found that you need a little &#34;give&#34; in the roller to get good foot positioning in order to effectively stretch your calves.  Second, even though this one has a bumpy texture, the finish is way too slippery.  This almost necessities wearing a sneaker or some kind of shoe, just to get a decent grip between my foot and the roller.  Finally, the bumps provide little to no added benefit, even if I don't wear a shoe.  Otherwise, this is as advertised, I.e. a high density, half-round, foam roller.
