Saddle Height / Setback / Length vs. Shoe Swap or Wearing 2 Pairs of Shoes!
The idea that changing shoes or wearing more than one pair of shoes at the same time makes no difference as long as the cleats are properly adjusted is wrong.
When buying new shoes, or if you use more than one pair on the same bicycle, you should pay attention not only to the fit of the cleats, but also to the shape of the shoe and the height of the sole.
In the example given, there were 2 pairs of shoes used by the same athlete on the same bicycle.
This makes adjusting the bicycle for both pairs of shoes impossible. Dado de que a altura de sola e modelo de sapatos são muito diferentes. This causes huge differences in the general fit of the bike, especially in terms of saddle height, setback and length.
