“…A targeted compression approach is essential for proper support and optimal blood circulation in every leg region. This customization considers the speci c anatomical needs of each individual[16, 24,25], adapting to variations in leg conformation. Maintaining pressure that respects these anatomical characteristics signi cantly contributes to overall well-being, avoiding the ine cacy of uniform compression and allowing for better management of each individual's physiological peculiarities.…”

Purpose Despite compression garments (CG) having acquired significant attention in the sports field, there remains ongoing debate regarding their actual effectiveness in enhancing athletic performance and expediting post-exercise recovery. This article delves into various aspects, with a focus on CG design and the materials they are made of, aiming to analyze the importance of personalized compression strategies based on individual anthropometric measurements and non-linear compression designs. Methods Through anthropometric analysis of 40 healthy participants, this study examined the morphological characteristics of the lower limb and their implications for CG design. Results Measurements of limb length and circumferences revealed complex interactions among anatomical variables, emphasizing the need for customized and adaptable device design. Finite element simulations further clarified the challenges in achieving uniform pressure gradients along the lower limb, highlighting the limitations of one-piece devices and suggesting tailored segmented designs for individual limb segments. Conclusion The results demonstrated that while one-piece devices may offer simplicity, they often fail to provide optimal compression due to non-linear variations in limb dimensions. Conversely, segmented devices, particularly those with bilinear progression, exhibited superior performance in applying targeted compression across different limb segments. This more detailed approach to customization could significantly contribute to optimizing outcomes and user comfort.

“…Setting of the lower leg material properties was an essential part of the finite element analysis. 26 The human body is a complex substance; however, the pressure exerted on the human body by compression garments is generally small. In order to simplify the calculation, this study set the lower leg at the top part of socks as an isotropic linear elastomer, and defined the skeleton density as 1850 kg/m 3 , elastic modulus as 7300 MPa and Poisson's ratio as 0.3.…”

How to achieve an effective balance between functionality and comfort is a key factor in the design of the top part of socks. In order to make the top part of socks more consistent with the characteristics of pressure distribution at the lower leg while improving pressure comfort, the lower leg and foot of the human body was taken as the research object, and Mimics software was used to establish a three-dimensional model of the lower leg and foot. ABAQUS software was applied to simulate the pressure distribution state of the lower leg at the top part of the socks and the stress trend in each region of the lower leg after wearing experimental socks. In order to further study the compression state of the lower leg section at the top part of the socks after wearing the socks, the section was divided into eight regions according to the angle, and the functional relationship between pressure and displacement was obtained through curve fitting. Meanwhile, the volume shrinkage of the eight regions of the lower leg section after compression was calculated, respectively. Results showed that the curvature radius of the lower leg, the thickness of the soft tissue and the position of the skeleton jointly affected the pressure and displacement values after wearing socks, and the distribution trend of volume shrinkage was different at each region of the lower leg section. The conclusion could provide the theoretical basis for the optimization design of the tightness degree of the top part of socks in different regions, and provide a data reference for the research and development of pressure socks that meet the required pressure comfort.

“…From the textile point of view, the main developments are new products of different compression classes [16,17] with graduated pressure [18] and improved comfort properties [19,20]. Important aspects are the prediction the compression value [21] and its mathematical modeling [22]. The development of reliable full body scanning has provided a new tool for compression garment design [23] and the study of the interaction between the body and clothing fit in active positions [24].…”

The high speed (4D) body scanning provides technical possibility for accurate measurements of the body geometry and can be applied not only for moving objects, but as well for evaluating the changes of static geometry with time. This information is important for compression socks, because it provides data regarding the relaxation processes of the textile product and of the human leg. In this work, changes of the body geometry after 1 and 4 hours with compression socks are investigated. Up to 9% changes of the cross section areas and up to 5.5% of changes of the circumference between the position at the starting point and after 4 hours are detected. Additionally the differences between the both legs of the investigated person and of the different (upper- and bottom) part of the leg are observed. It is the first step to the digitalization of the personal compression stocking design.
