The importance of well-functioning toes has long been recognised but has not previously been assessed in biomechanical studies. We have examined the weight-bearing function of the foot in 160 normal subjects by use of the pedobarograph. The function of the toes was assessed by reference to the time they were in contact with the ground and the peak pressures they exerted individually in comparison with other parts of the foot. The toes were in contact for about three-quarters of the stance phase… 

The Effect on Gait of the Lack of Ground Connection by the Toes in Standing

TLDR
The people who have a floating toe deformity do not build a base of support, and it is difficult to move the center of foot pressure forward when walking, and these deformities can cause foot alignment anomalies.

Evaluation of toe function based on the plantar pressure distribution while walking and its relationships with general gait parameters

TLDR
A method to identify the boundary position between the toe and foot based on the foot pressure distribution matrix was applied to gait analysis and suggested that the toe area ratio may reflect gait function and aging.

Pressure and force distribution characteristics under the normal foot during the push-off phase in gait

TLDR
The plantar pressure distribution during the push-off phase of walking was measured with the EMED-SF4 system of Novel in 42 healthy subjects between 20 and 59 years of age and showed that the big toe and the region of the sole under the second metatarsal head (MTH2) exhibited the highest pressures.

Adjustments in the Range of Angular Motion during Walking after Amputation of the Toes: A Case Report

TLDR
Results are consistent with the important role of the forefoot (tarsals and metatarsophalangeal joints) and suggest that footwear can facilitate gait function following toe amputation.

Relationship between Toe Flexion Movement and Center of Pressure Position

TLDR
It is suggested that the ability to flex the toes with extended interphalangeal joints affects stability in the static standing position, and the toe flexion angles and force of pushing against the floor affect dynamic balance.

Walking, running and the evolution of short toes in humans

TLDR
A biomechanical model of toe function in bipedal locomotion is proposed that suggests that shorter pedal phalanges improve locomotor performance by decreasing digital flexor force production and mechanical work, which might ultimately reduce the metabolic cost of flexorforce production during bipedAL locomotion.

Kinematic gait analysis of a young man after amputation of the toes

TLDR
Investigation of gait kinematics of a man after bilateral partial amputation of the toes found changes in gait due to the forefoot dysfunction may be stabilizing adaptations related to fear of falling.

The Kinesiological Effect of Japanese Geta Clogs on Gait: A Pilot Study

TLDR
The results suggest that active toe movement occurs during Geta gait, and the use of Geta clogs may contribute to preventing foot disorders and falls.

The foot has been studied in walking, running and jogging using high speed cinema photography in the laboratory for gait analysis in the Shriner's Hospital for Crippled Children, San Francisco.

Anatomy of the forefoot, normal and pathologic.

TLDR
For the kinematics of the foot, for the stability of the arches, and for the ability of the skin to withstand shear forces, it is important to select a shoe that does not compress the toes, restrict their movements unnecessarily or expose the metatarsal heads to uneven pressure.

Forces under the hallux valgus foot before and after surgery.

TLDR
The changes in the relationships between the loadings on the forefoot and skeletal shape in response to surgical operations are important for the understanding of treatment of the hallux valgus foot.

A Clinician's View of Foot Pressure: A Comparison of Three Different Methods of Measurement

TLDR
Three commercially available systems for measuring the pressure distribution under the foot have been compared by measuring ten “normal” subjects with these different techniques to show the differences between the equipment and the results and help investigators interested in foot problems to choose the best system for their particular needs.

The Measurement of Pressures under the Foot

An apparatus is described which gives a rapid and detailed picture of the distribution of pressure under the foot, this being displayed either as a continuous grey scale or a color contour map on a

TLDR
In hallux valgus in the adult, arthroplasty offers a reasonably good solution in the well chosen case, though no one should consider that the results are so good as to make unnecessary any further research in this field.

Use and Abuse of Toes

TLDR
The mystic is just as much with us to-day as he was in the past, though his mysticism now takes other forms, and is rarely, if ever, founded on the visual phenomena of migraine, but the influence of the seers and prophets of the past is still strong, not only on him, but also on a very large proportion of the authors' contemporaries.
