Due to our weight impacting these inserts every day, should they be replaced every so often? Does the effectiveness wear off the longer I use them?

I have several sets of these cups the oldest of which is a few years old. The cup part gets distorted by the shoes I wear but the bottom waffle part which is the energy-absorbing part doesn't look mashed (and I weigh 220+). I haven't noticed any loss of effectiveness.

They are better than the regular insert that comes with the shoe. You can definitely feel a difference. It's not much but it's better.

I have had mine for a good year and a half of constant wear. Its a little worn down but still going. I would say about 1-2 years of every day wear before replacement

Mine are still effective after over a year of use and I still use it. Make sure to keep it indoor because it has the tendency to thickened.

Only when they crumble or break down. Otherwise you should not replace them.

I have not had any problems, I go to the doctors offices weekly, and the are identical each time with my set at home. You may need to get them replaced?

I have been using them for 2 years. if you use them twice a day they will last 30 days. You than need to replace them. I don believe it is permanent, you will have to continue on a maintenance program I sometimes forget, but most of time I use them at least once a day I hope this helps by iluvmath65@yahoo.com

I've had mine about a year, use them every day for at least 3 or 4 hours. Still perfect.

I change mine all the time by hand - never had a problem. These have worked well for me.

I have had mine for more than a year and they show no wear at all. they fit as well as the ones I paid much more for from my dentist, but couldn't use anymore because I had work done to my teeth that changed their shape so that my original tray would fit.

Oh, gosh. It's been a couple years since I used them. I do remember, though, that they were no heavier than the ones I left the hospital with. But again, I don't know what is currently available, so that's not much help. I will say, though, that unless they have come out with something better since then, I'd use them again. hey really did absorb some of the weight/shock.

Deborah is exactly right! I've been using these pillows for more than 15 years, and the quality and life of the pillow has declined substantially over that time. I've bought new ones every few years. The old ones lasted much, much longer than do the current ones.

I've purchased mine a few years ago and still good for me and was regularly used. I have not replaced so far.

I believe they would last until the elasticity in the band becomes too weak to apply enough pressure. I have not had any wear out yet.

It's hard to say. My wife hasn't replaced hers since we purchased them in December, but she doesn't do it every night either. Couple of times per week.

I don't know how often you use them but I have had some for up to 6 months and haven't any trouble with them. Hope this has been helpful. Thanks Bert
