BACKGROUND:
Both walking and running contains the same cyclical movement phases, however, they differ greatly in time proportions, as well as magnitude of acting forces. The objective of this study was to ascertain that the regular jogging activity induced the adaptive modifications of foot pressure distribution pattern in fore-aft and lateral-medial dimensions during walking for female joggers.
METHODS:
The research base consisted of 96 women between 20 and 50 years of age; and included 50 female active joggers, and 46 of female non- joggers. The study was performed with the use of a EMED-SF force platform. Two parameters describing the plantar surface of the foot loading were established, namely force time integral (FTI) and pressure time integral (PTI). Two indicators were defined: percentage medial impulse acc. to Bowen and metatarsals and toes loading ratio acc. to Nagel.
RESULTS:
Our study showed lower PTI and FTI for the both feet big toes in the female joggers group. What is more, our research results indicate that regular jogging increases loading of metatarsus and lateral side relatively to toes and medial side, respectively.
CONCLUSIONS:
The observed differences in foot pressure distribution patterns in both groups included in the current study proved the substantial influence of jogging on adaptive functional changes of walking pattern.

I going to call BS on the conclusions of this study and have written a blog post on it .... but it was just based on the abstract, so waiting to get hands on full paper before publishing it (in case I jumped to the wrong conclusion!)

Difference of walking plantar loadings in experienced and novice long-distance runners
Zixiang Gao et al
Acta Bioeng Biomech. 2020;22(3):85-93.

aimed to evaluate the differences in plantar loading between experienced long-distance runners and novice runners during walking. The hypotheses were that smaller load in the middle of the forefoot and the stable foot balance would be observed in experienced runners during walking.

Methods: Twenty-five participants were recruited as the experienced runners group (ten: frequency ≥ 4 times/week and distance ≥ 40 km/week, for over 1 year) and the novice group (fifteen: frequency ≤ 2 times/week and distance ≤ 10 km/week, for less than 1 year).

Results: The peak Meta loading showed that the novice runners were significantly larger than the experienced runners ( p ≤ .001). The occurring time of peak Meta loading was significantly delayed compared to the experienced runners ( p = .050). Peak Foot balance was higher in the novice runners group ( p ≤ 0.001).

Conclusions: This study highlighted the findings of the potential differences of plantar pressures and foot functional parameters during walking in experienced runners and novice runners, specifically the contact duration of phases during stance, toes functions and medial-lateral loading shifting (foot balance) and metatarsals (central forefoot) offloading.
