Abstract: The mid-tarsal break is a biomechanical feature found in some primates, enabling flexibility in the midfoot region during locomotion. This concept has attracted attention in the study of alleged Sasquatch footprints, as enthusiasts and some researchers argue that it provides evidence for the existence of the elusive creature. This article aims to examine the anatomical and functional aspects of the mid-tarsal break, explore its evolutionary significance, and critically evaluate its application within Sasquatch research.
1. Introduction
The study of Sasquatch, or Bigfoot, has long existed on the fringe of mainstream science. Enthusiasts and cryptozoologists claim that physical evidence, such as footprints and alleged sightings, suggests the existence of a large, bipedal primate living in remote regions of North America. One of the more intriguing aspects of Sasquatch footprint evidence is the mid-tarsal break, a biomechanical feature observed in some prints that resemble those of large hominins and non-human primates. This article will review the current understanding of the mid-tarsal break in primates and its relevance to Sasquatch research, focusing on how it has been used to substantiate claims about the creature's existence.
2. Anatomy and Function of the Mid-Tarsal Break
The mid-tarsal break refers to the ability of the midfoot to flex independently of the forefoot and heel during walking. It is a common feature in non-human primates such as chimpanzees, gorillas, and other apes, who possess a highly mobile and flexible foot structure. In these primates, the mid-tarsal break facilitates efficient climbing and allows for greater adaptability in uneven or rugged terrains.
Humans, by contrast, have a more rigid arch in the foot that contributes to the energy efficiency of bipedal walking. The longitudinal arch in humans functions as a spring mechanism, storing and releasing energy during each step, providing stability and support over long distances. The rigid structure of the human foot is one of the defining features of our obligate bipedalism, making mid-tarsal breaks a rare or nonexistent occurrence in typical human locomotion.
3. Evolutionary Context
The mid-tarsal break is thought to be a vestigial remnant of our arboreal ancestry, present in species that required greater foot flexibility for climbing. This adaptation is observed in some of the earliest hominins, such as Australopithecus afarensis (e.g., "Lucy"), whose foot structure combined traits of both arboreal and terrestrial locomotion. Fossil evidence suggests that early hominins likely possessed more flexible midfeet than modern humans, indicative of a transitional stage between arboreal and fully bipedal lifestyles.
Thus, the presence of a mid-tarsal break in a hominin would suggest a more primitive foot structure, one that is suited to both terrestrial and arboreal environments. For cryptozoologists, this becomes a key point in analyzing purported Sasquatch footprints, as it could suggest the existence of a non-human primate or hominin with an evolutionary trajectory distinct from that of modern humans.
4. Sasquatch Footprints and the Mid-Tarsal Break
In Sasquatch research, one of the most frequently cited pieces of evidence is large, humanoid footprints, often found in remote forested areas. Some of these footprints show characteristics that enthusiasts claim are inconsistent with modern human anatomy, including wide spacing between the toes, an enlarged heel, and most notably, the presence of a mid-tarsal break.
The argument for a mid-tarsal break in Sasquatch footprints is largely based on the work of Dr. Jeffrey Meldrum, a professor of anatomy and anthropology, who has extensively studied purported Bigfoot tracks. Meldrum and others argue that some of these footprints display features consistent with a flexible midfoot, similar to that seen in non-human primates, which would allow for increased adaptability and shock absorption when traversing rugged terrains.

5. Critical Evaluation of the Evidence
Despite these claims, there is significant skepticism within the scientific community regarding the interpretation of Sasquatch footprints and the mid-tarsal break. Several key points must be considered in evaluating this evidence:
Footprint Authenticity: Many alleged Sasquatch footprints have been dismissed as hoaxes, either fabricated by individuals or misinterpreted from natural phenomena, such as overlapping human or animal tracks. The presence of a mid-tarsal break in some footprints could simply be the result of irregularities in the substrate or the result of slippage when the footprint was made.
Human Variation: While rare, some modern humans with flat feet or other orthopedic conditions can exhibit midfoot flexibility that might resemble a mid-tarsal break. These instances, while uncommon, challenge the idea that a mid-tarsal break is entirely absent in human anatomy and question its exclusivity to non-human primates or cryptids.
Lack of Consistent Evidence: Sasquatch footprints displaying a mid-tarsal break are not uniformly found, even among collections of alleged prints. The inconsistency in this feature raises questions about whether it is truly a reliable marker of a non-human creature or simply a variation that can occur under specific conditions.
Alternative Explanations: Some researchers propose that footprints exhibiting a mid-tarsal break could be explained by known species, such as bears, whose footprints can overlap in ways that mimic bipedal walking and create impressions that resemble those of a large, humanoid creature.
6. Conclusion
While the mid-tarsal break is an interesting feature in primate biomechanics, its application to Sasquatch research remains speculative. The existence of Sasquatch is not supported by conclusive physical or genetic evidence, and the interpretation of footprints with mid-tarsal breaks should be approached with caution. The feature itself is well-understood in the context of primate locomotion and evolution, but its relevance to Sasquatch footprints hinges on the authenticity of the tracks in question.
Further research into purported Sasquatch footprints, combined with rigorous field investigations and modern techniques like DNA analysis, would be necessary to provide any credible support for the existence of an undiscovered large primate species. Until such evidence emerges, the mid-tarsal break remains an intriguing but ultimately inconclusive element of Sasquatch lore.
