Shape And Size

Foot Problems NORMALLY the foot functions differently in stance than it does in motion. During stance, static stresses are most important. The foot may be divided at the midtarsal joints into the hindfoot which receives 60 per cent of the weight-bearing stress and the forefoot which receives 40 per cent of the stress. The spring ligament normally transmits the stresses from hindfoot to forefoot. All degrees of foot shape and size may be natural for a particular individual. Similarly, the gait pattern of a child varies considerably within the normal range. The child should be allowed to establish his own normal gait pattern. During the toddling stages the child's shoe soles should be flexible enough to bend at the toe. One should avoid the use of rigid shoes. Some of the conditions which may alter normal stance or gait follow. Simple Foot Strain Long arch strain is due to abnormal stress on the longitudinal ligament. Inflammatory repair of the ligament produces pain which can be demonstrated by finding an area tender to palpation. Some patients have a depressed longitudinal arch or long spring ligament without foot symptoms. A diagnosis of long arch strain cannot be made unless tenderness is present. A tight heel cord may produce foot strain. The foot accommodates to a tight heel cord by pronation of the forefoot. To correct a tight heel cord, the child should stand away from the wall (while facing it) with the heels flat, then lean forward count to 3. Repeat 5 times twice daily. Pronation

CONTEXT AND OBJECTIVE: In basketball, the most common injuries are ankle sprains. For this reason, players frequently use external ankle devices or taping as prophylactic and rehabilitation measures. The purpose of this study was to evaluate ground reaction force (GRF) responses in basketball players while performing typical cutting maneuvers with and without ankle bracing and ankle taping. DESIGN AND SETTING: Comparative study with experimental design of single-group repeated measurements, at Medical Rehabilitation Division, Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo. METHODS: Vertical (Fy) and medial-lateral (Fz) GRF measurements were made under three conditions (taping, Aircast-type orthosis and basketball shoes alone), with analysis of peak forces at foot contact (Fymax1, Fzmax1, Fymax2 and Fzmax2), growth gradient (peak/time) (GG Fymax1, GG Fzmax1, GG Fymax2 and GG Fzmax2) and impulse after foot contact. RESULTS: Bracing significantly reduced Fymax2 and GG Fymax2. GG Fzmax1 was significantly higher for the sport shoe condition than for the taping condition. Taping increased Fy in relation to the sport shoe at foot contact, but over a longer time interval, without increasing excessive ankle loading. Fz reached a peak in less time, which might generate greater inversion/eversion loading on a player's foot. The Aircast exerted better shock-absorbing effect than did the other two conditions, since it generated less vertical force over longer time intervals and smaller medial-lateral forces in relation to taping. CONCLUSIONS: Ankle bracing and ankle taping action mechanisms are still unclear and therefore should be carefully prescribed. More studies are needed to clarify taping and bracing effects on sporting activities.

Original Device

The paper refers to an original device, designed by the authors, which provides cleaning for shoe soles when a person enters into a home. This device resembles an ordinary scale and provides cleaning without causing pollution. It is composed of a flexible strip with a brush on the active surface. The dirt is collected by means of tabs that allow its storage in a drawer cell. The device has a simple structure, but originally, it is different from other similar products available worldwide. It is easily accomplished by using existing components (eg. a drill with helical gear). It is easy to maintain and can be powered from any AC grounded outlet 220 V.

Polyuretanes are widely used as elastomers, coatings, adhesivesand binders,interior and exterior cars, furniture,shoe soles, carpets, rigit and flexible foams, membrane materials as well as constuction materials .The production of polyurethanes is largely derived  from  polyols derived from petroleum . Howover, petroleum  is a non- renewable raw material . Thus it is necessary to look alternative feedstock  for the manufacture of polyol  as a polyurethane raw material. Synnthesis polyurethane by polymerization process  using  polyol volume based on polyol  oleat acid  polypropylenglycol ( PPG ) in order to know  whether fatty acid can be used  as raw materials  of polyurethane manufacture.From the result of the study. Based on Fourier Transform Infra  Red ( FTIR), showed,that the product  produced is polyol with obtained hydroxyl  group ( OH group )with hydroxylnumber is 129,81 mg KOH / g and 157,60 mg KOH / g sample of 70

Shoe Soles

On the basis of computer aided modeling technology, this paper proposes a porous structure modeling method based on Grasshopper visual programming language and Unigraphics NX (UG) secondary development platform. The finite element model of the foot was established, and then models of shoe soles with four basic porous structures of cross, diamond, star, and x were established. Each structure was set with a cylindrical radius of 1, 2, and 3 mm, and a total of 12 porous structure sole models were established. The shock absorption effect of the sole on the foot was evaluated by the deformation of the sole, the peak plantar pressure, and the peak stress of metatarsal bones. It is found that the maximum value of the sole deformation of the diamond porous sole is 4.725 mm, the peak plantar pressure is 105.1 Pa, and the first and second metatarsal peak pressures are 2.230 MPa and 3.407 MPa, which have the best shock absorption effect. It shows that the porous structure plays an important role in the cushioning of the sole. The biomechanical effects of porous soles on feet are studied by computer-aided technology and finite element analysis. This study provides a new research method for the cushioning design of shoe soles and has important reference value for the design of footwear.

Quantitative Basis

Purpose This paper aims to provide a quantitative basis to analytically determine the ranking of the brand personality of Adidas, Asics, Nike, Puma and Saucony brands among Iranian customers via a conventional multi-criteria decision-making (MCDM) method. Design/methodology/approach Data for determining the importance of evaluation criteria and ranking of brands are gathered by means of distributing questionnaires among a group of Iranian customers of sport shoes, as well as some industrial experts. The fuzzy analytic network process (FANP) was used to rank the brands with regard to dependencies between criteria and alternatives. Findings The results indicate that FANP is a capable method which provides invaluable insights for strategic marketing decisions in the sport product industry. Results show Adidas has the best performance in the sports shoe market compared to the other four brands. In this study, it was found that expertise sophistication was the most important criterion among Aaker’s five main criteria. Originality/value The value of this paper is applying FANP decision-making method for ranking sport shoe brands. This method has not been commonly used in the area of marketing, hence it is added to the pool of techniques used in ranking brands. In addition, evaluation and ranking of brands can be very useful for both academic research and practice. Researchers can benchmark the competences of each brand through evaluating them, and industrialists can extract the competitive advantages of the selected brands.
