Magnetic hock boots

[ahlam1399]

I am sure this has been done to death but I wonder what people's thoughts are on magnetic hock boots for a horse with spavins?She is 12 and developed them as a 5 year old. Through winter, and especially at this point where they have had to be in for a while (some turnout but only minimal) she is getting stiff when she comes out in the morning. Do people think they would help in this instance? I was thinking maybe they should be worn overnight?
