I had the shoes for a few weeks and everything from walking on the treadmill to my everyday work of up and down stairs they fill the bill in every case. I recommend putting your fingers underneath the foam and pushing the plastic disc with your thumb. Now the HK255 has done away with the flip altogether, which is the only good thing about this unit. Over all- I dont regret buying 2 pairs of these and would buy again if I had to do all over again. Functional storage and great value make this rail a great choice. These didn?t work for me. Now, its a rolling paper weight. Initial review 3/8: I use this headset for my Xbox One. She was able to get rid of most of the cables by her night stand. All the shirts are medium sized and had to be bunched at the bottom, not recommended for dress shirts.
