The niggles Ive been having in my calves are definitely easing (bearing in mind Ive only had the Yoback fir a couple of weeks). And the issues Ive been having with I think are a side effect of calf issues are also easing!
Top tip - if youre worried you may buy them then not use them, I keep them in the bathroom and do stretches morning and night while Im brushing my teeth.
