I have a chronic shoulder problem & have had multiple surgeries leaving me with severe shoulder pain, mainly in the area directly under my bra strap & a bit of a dropped shoulder. This & big boobs meant that wearing a bra was a nightmare as it hurt like hell & the strap would continually fall off my affected shoulder. Tightening the strap didn't work as this just put more pressure & pain on my shoulder! Have been thinking about these strap cushions for a while & was a little put off by some of the reviews, but for the price thought they were worth a go.
I'm so glad I did, what an immediate difference... Vastly reduced pressure on my shoulder & the strap now stays in place as long as I'm wearing it! The strap cushions are great & will take a variety of strap widths - mine tend not to be skinny straps! If I'm wearing a vest top, you can see some of the clear silicone, but for me this is not an issue - it's the comfort which works for me. I also find on a hot day that my shoulder gets a little sweaty underneath the cushion which can make it slide around a bit, but nothing too drastic & I just give it a wipe when I head to the loo.
Overall, I am so happy with these - they have made a huge improvement to my life!
