The only athletics event that's limited design advantages is the javelin, and that's only because they were nearly throwing it into the stands.
Show up to a sanctioned track race with 12 spikes in your shoes and let me know how javelin's the only event with design limitations...
IAAF COMPETITION RULES 2018-2019
Shoes
2. Athletes may compete barefoot or with footwear on one or both feet.
The purpose of shoes for competition is to give protection and
stability to the feet and a firm grip on the ground. Such shoes,
however, must not be constructed so as to give athletes any unfair
assistance or advantage. Any type of shoe used must be reasonably
available to all in the spirit of the universality of athletics.
Note (i): Adapting a shoe to suit the characteristic of a particular
athlete’s foot is permitted if made in accordance with the general
principles of these Rules.
Note (ii): Where evidence is provided to the IAAF that a type of shoe
being used in competition does not comply with the Rules or the
spirit of them, it may refer the shoe for study and if there is
non-compliance may prohibit such shoes from being used in
competition.
Number of Spikes
3. The sole and heel of the shoes shall be so constructed as to provide
for the use of up to 11 spikes. Any number of spikes up to 11 may be
used but the number of spike positions shall not exceed 11.
Dimensions of Spikes
4. That part of each spike which projects from the sole or the heel shall
not exceed 9mm except in the High Jump and Javelin Throw, where
it shall not exceed 12mm. The spike must be so constructed that it
will, at least for the half of its length closest to the tip, fit through a
square sided 4mm gauge. If the track manufacturer or the stadium
operator mandates a lesser maximum, this shall be applied.
Note: The surface must be suitable for accepting the spikes
permitted under this Rule.
The Sole and the Heel
5. The sole and/or heel may have grooves, ridges, indentations or
protuberances, provided these features are constructed of the same or
similar material to the basic sole itself.
In the High Jump and Long Jump, the sole shall have a maximum
thickness of 13mm and the heel in High Jump shall have a
maximum thickness of 19mm. In all other events the sole and/or heel
may be of any thickness.
Note: The thickness of the sole and heel shall be measured as the
distance between the inside top side and the outside under side,
including the above-mentioned features and including any kind or
form of loose inner sole.
Inserts and Additions to the Shoe
6. Athletes may not use any appliance, either inside or outside the shoe,
which will have the effect of increasing the thickness of the sole
above the permitted maximum, or which can give the wearer any
advantage which he would not obtain from the type of shoe
described in the previous paragraphs.
