This is mainly a rant post.
Why must it be so painful to get the cleat position right on a new set of shoes!?!
No matter how you measure it - it’s always wrong
I suspect the stack height is a fraction higher on the new shoes which doesn’t help things!
I think it has more to do with the shape of the new shoes and the effect of that over the measurements.
Can anyone help to explain this?
Hip → Knee → Ankle angles
Top of pedal stroke.
Old shoes - 81 degrees
New shoes - 80 degrees
New shoes - saddle up 3mm 77 degrees
Guessing some measurement error - but I’m going to assume the only difference can possibly be ankle movement? I would have expected that saddle going up would increase the angle rather than decrease.
I realize this is an old post. Searching for something else and and saw this. Just interested…Are you frustrated with cleat position as in alignment? I use this if so:
Or are you frustrated with the difference in stack from shoe to shoe due to sole thickness? If so I just find the center of the first metatarsophalangeal joint and mark the shoe with a paint pen. Put the shoes on a level surface and measure up to that point. A new pair of Vittoria shoes measures about 5mm less than my DMT’s.
