“…The relationship between foot map marking of plantar discomforts and locations of increased plantar pressures showed no relationship for most foot regions and only weak relationships at the medial and lateral forefoot regions. It was demonstrated by Santos et al (2001) that higher plantar pressures occur when wearing football boots in comparison to running shoes due to the decreased plantar surface area in the football boot. Other varying factors between football boots and running shoes include the built-in cushioning in running shoes as well as the traction features required for football boots due to the more multi-directional manoeuvres performed.…”

“…Compared to running shoes, no cushioning support is provided, the outsole studs distribute pressures differently and the soles are usually cut narrow to permit better sensation of the ball along the instep. These differences in footwear design have been shown to create around 35 % higher forefoot plantar pressures when walking in football boots in comparison to running shoes (Santos et al, 2001). The high plantar pressures seen in football boots are believed to cause an increased risk of metatarsalgia and metatarsal stress fractures (Debiasio et al, 2013;Eils et al, 2004;Queen et al, 2007;Sims et al, 2008;Warden et al, 2007).…”

“…For football boots, the relationships between plantar pressures and athletic drill (Debiasio et al, 2013;Queen et al, 2007;Sims et al, 2008;Wong et al, 2007), sex (Debiasio et al, 2013;Sims et al, 2008), surface type (Ford et al, 2006), and different boot designs (Bentley et al, 2011;Santos et al, 2001) have previously been investigated. However, only one study (Nunns et al, 2015) has been conducted on the relationship between objective measures of plantar pressure and subjective data for football boots.…”

Context: Stress fractures are one of the most common injuries in sports, accounting for approximately 10% of all overuse injuries. Treatment of fifth metatarsal stress fractures involves both surgical and nonsurgical interventions. Fifth metatarsal stress fractures are difficult to treat because of the risks of delayed union, nonunion, and recurrent injuries. Most of these injuries occur during agility tasks, such as those performed in soccer, basketball, and lacrosse.Objective: To examine the effect of a rigid carbon graphite footplate on plantar loading during 2 agility tasks.Design: Crossover study. Setting: Laboratory. Patients or Other Participants: A total of 19 recreational male athletes with no history of lower extremity injury in the past 6 months and no previous metatarsal stress fractures were tested.Main Outcome Measure(s): Seven 458 side-cut and crossover-cut tasks were completed in a shoe with or without a fulllength rigid carbon plate. Testing order between the shoe conditions and the 2 cutting tasks was randomized. Plantarloading data were recorded using instrumented insoles. Peak pressure, maximum force, force-time integral, and contact area beneath the total foot, the medial and lateral midfoot, and the medial, middle, and lateral forefoot were analyzed. A series of paired t tests was used to examine differences between the footwear conditions (carbon graphite footplate, shod) for both cutting tasks independently (a ¼ .05).Results: During the side-cut task, the footplate increased total foot and lateral midfoot peak pressures while decreasing contact area and lateral midfoot force-time integral. During the crossover-cut task, the footplate increased total foot and lateral midfoot peak pressure and lateral forefoot force-time integral while decreasing total and lateral forefoot contact area.Conclusions: Although a rigid carbon graphite footplate altered some aspects of the plantar-pressure profile during cutting in uninjured participants, it was ineffective in reducing plantar loading beneath the fifth metatarsal.Key Words: soccer, cross-cutting, side cutting, plantar pressure, fifth metatarsal fracture, rigid carbon graphite footplate Key PointsFifth metatarsal stress fractures can be difficult to treat because of the risks of delayed union, nonunion, and recurrent injury. In combination with a custom orthotic and foot brace, modifying footwear with the use of a carbon graphic footplate has been proposed to allow athletes to safely return to sport while the stress fracture is healing. Plantar loading beneath the fifth metatarsal increased in healthy participants who wore a carbon graphite footplate while performing agility tasks. Plantar loading with and without the footplate should be studied in patients with metatarsal fractures. W hile athletes compete in sports, the risk of injury depends upon the sport and position being played.1 Age, sex, competition level, bone density, and shoe type are all risk factors for injuries related to the foot and ankle.2-4 Stress fractures are one of the most ...

“…This equipment can be used in clinical, rehabilitation, and sports fields in order to assess patterns of forces between the agent and the ground (Hughes et al, 1991;Santos et al, 2001;Ribeiro & Mota, 2004). Compared with force platforms, pressure insoles have the advantage of measuring the PP directly applied to the foot during less constrained tasks and may be used to assess other parameters like force distribution along the plantar region or between right and left foot, including outside the laboratory, with relatively ease.…”

Mechanical load has been estimated during step exercise based on ground reaction force (GRF) obtained by force platforms. It is not yet accurately known whether these measures reflect foot contact forces once the latter depend on footwear and are potentially modified by the compliant properties of the step bench. The aim of the study was to compare maximal and mean plantar pressure (PP), and maximal GRF obtained by pressure insoles after performing seven movements both over two metal force platforms and over the step bench. Fifteen step-experienced females performed the movements at the cadences of 130 and 140 beats per minute. PP and GRF (estimated from PP) obtained for each floor condition were compared. Maximal PP ranged from 29.27 ± 9.94 to 47.07 ± 12.88 N/cm2 as for metal platforms, and from 28.20 ± 9.32 to 43.00 ± 13.80 N/cm2 as for the step bench. Mean PP ranged from 11.09 ± 1.62 to 14.32 ± 2.06 N/cm2 (platforms) and from 10.71 ± 1.54 to 14.22 ± 1.77 N/cm2 (step bench). GRF (normalized body weight) ranged from 1.43 ± 0.14 to 2.41 ± 0.24 BW (platforms) and from 1.38 ± 0.14 to 2.36 ± 0.19 BW (step bench). No significant statistical differences were obtained for most of the comparisons between the two conditions tested. The results suggest that metal force platform surfaces are suitable to assess mechanical load during this physical activity. The forces applied to the foot are similar to the softer step bench and the hard force platform surface. This may reflect the ability of the performers to adapt their movement patterns to normalize the impact forces in different floor conditions.
