I found this one on amazon. It's a link from Amazon, but the manufacturer, Sportline, seems to have a number of other options as well. Sportline Water Bottle Holder This one might be useful as it also holds keys, phone, etc.
Otherwise, if this one doesn't work for you, they have other options on their main site: Sportline
Has anyone tried those Skechers "Shape Up" shoes? (Or similar ones.) They're the ones with the thick soles that are supposed to magically firm your derriere. Are they comfortable? Safe? Do they help firm anything?
We were on vacation when I saw a pair of Z-coils for the first time. Had no idea what they were. They sure are interesting looking. I asked a granddaughter about the Sketchers; she hasn't gotten back to me, yet. I'll ask one of her sisters. If I get an answer, I'll let ya know.
Sandy N. My southern belles just got back to me and they say their mom loves her Sketchers. I'm told she wears them all the time. IMO, the design of the Z-coils look easier to adjust to. But I imagine it's a matter of preference. Good luck in whatever you decide. Prayers and blessings,
I didn't buy any yet and don't seem to need them. I am so much stronger just walking everyday. I truly believe walking is the best exercise for anyone.
