I think they are the ones with springs in the sides, such as the Sprenger ones (they're £100 though!). There are cheaper versions out there too, for example www.robinsons-uk.com do some for £25.
I have the Sprenger ones and they work for me. My anckle and knee used to ache within half an hour, but they are still fine no pain even after 5 hours. Have heard tha the cheaper ones are not so good, but I haven't tried them so cant comment
Flexi stirrups.I got some at Badders and my god they don't arf help.i got the Mark todd ones and they were £22.50.Highly recomend them.My knees are much better when riding.And when i get off i dont feel so much like John wayne.
There are two types those with hinges and those with springs. Technically the springs ought to be better as they take the shock out of a horses stride, whereas the hinge just move to relieve pressure.
Springs are
T6
Metalab
Hinge are:
Sprenger (both types)
Shires
Royston
Westgate (Mark Todd)
Thanks for that!! Ive only ever had ordinary irons and when I read on here that there were some that helped with knee pain .... well just had to get some!!! I dont tend to spend much on me whilst presshus horse gets the best!! So its about time I spoilt myself! Plus i feel like a bit old and doddery at the mo!! Really I should see a surgeon but that would be too traumatic!!! Dont do surgeons!!
I think it is between the new sprenger irons and the T6!!! Theres not a lot of difference really in price in the great scheme of things!! Just seems a lot to pay for a bit of metal!!!!
Thanks so much. I'll let you know if I walk without a limp again!!!
