The widest part is still on the top.
I first bought the recommended length (according to my height, 5’3+") and when I put the leathers at my riding length I had just one hole left for adjustment when my leathers were at a comfortable riding length. The end of the stirrup leather was NOWHERE near the loop on the flap to keep it out of the way and it ended up poking me in the thigh, mildly uncomfortable and quite distracting
The first pair I bought was at the recommended 125mm, recommended on the basis of the chart (I am 5’3+") and recommended when I finally got someone on the phone.
After my initial disappointment I got in touch with Millbrook asking for information about how long the wide part of the stirrup leather was for each length of the stirrup leather. She replied and the 115mm leather’s wide top part was 12" long, the 125mm leather’s top wide part was 13" long. I had already determined that from where the leather crossed my shin bone I needed the wide part to be 2 inches longer.
The solution was easy, the 145mm stirrup leather would end up with the widest part of the leather crossing my shin. Ever since I got the longer leather I LOVE these stirrup leathers!
I ride Forward Seat but I do not jump (I have MS and I just do flat work). If I was jumping, especially over 3’6", I would have had no trouble with the leathers, 3 holes shorter and my lower legs would have been happy.
Another part of my “problem” is that to keep my seat in the right part of the saddle (17"–3 saddles) I have to have my leathers one hole longer than the recommended ankle bone length.
Even though I had to pay full price for two pairs of the Millbrook leathers to get one pair that fit me I STILL think my pair of leathers is worth every penny I spent on them because I am more secure in the saddle. Lately my proprioceptive sense had gotten worse (I do not “know” where my different body sections are) and my sense of balance has deteriorated, and my riding teacher has only mentioned my lower leg once or twice in the past 2 months. On the other hand she HAS been commenting on the position of my hands when I can no longer “feel” where they are in 3-dimensional space. With normal stirrup leathers it was the opposite, on my bad days I got about the same amount of comments about my hands and almost CONSTANT comments about the position of my lower legs.
My riding teacher is a saint. Even after a decade she never gives up with correcting my position as my MS messes up my central nervous system, she never loses patience with me, and she realizes that the days I am TIRED mean that she gets to see me walk the horse for 30 minutes, not very entertaining!
