Speaking of caged stirrups. I wanted some, but already had some aluminum 
  easy ride and being a pennypincher I decided to retrofit mine. Since I have 
  plantar facidas(spell) and metatarsial something or other I have  feet 
  problelms and need all the help I can get.(oh and the 2nd degree ankle tear, 
  and inheritated weak ankles to begin with and I use d to do track)(Following 
  the shoe/boot thread too, as my ariats are dying and they really don't work 
  for lots of walking, climbing.) 
    So  I had my husband drill holes down the sides and two in 
  the bottom  right under the front . I bought 1/4 round head screws and , 
  acorn nuts. I bought heavy webbing like you see on straps on horse 
  blankets(fabric store, walmart or Home Depot type store , in automotive too, 
  you can use "tie down" straps )I then made an x with the straps and also 
  placed a piece  horizontal------ across the bottom and top  and 
  sewed it with uphostrey thread  (again wallmart  or fabric 
  stores) back and forthe tons of times. I then burned the edges to seal them 
  (candle) and used my sons sodeiring iron to burn holes in them . I then 
  screwed  the webbing spider web to the stirrups.
     Now be sure to cut the webbing long. I made a mistake and 
  cut my first ones too short and couldn't double it under the screws like I 
  wanted, (burn two holes and double it if you want extra strength. Mine 
  are on the second hole because I didn't cut the webbing long enough. Cut all 
  the pieces first and pin or tape them together to make sure the cage is bulgie 
  enough for your toe.   Should cost about 3-7.00$ You could use 
  salvaged webbing from an old horse blanket, straps , etc.Make sure you tighten 
  down with pliers and screwdriver, could use lock tight if you are sure they 
  fit.    
     Beats 95.00 for new stirrups.
