They are places of social interaction where the complexities of urban life flourish in an amalgamation of crashes and encounters. But sidewalks are not neutral scenarios where things happen. The way the sidewalks are made, the elements used, and the logic behind their (re)designs, play a crucial role in the development of those social interactions. Precisely, this number of Tarde is about the material and structural dimensions of sidewalks.<\/p>\n\n\n\n<p class=\"alignwide wp-block-paragraph\">Particularly, it will pay attention to a bunch of sidewalks in western Medell\u00edn, Colombia, focusing on their enactments and compositions. Those sidewalks have the structural peculiarity of being broken, damaged, turned into something else, and even usurped, but somehow still functioning as sidewalks. Together, they form an overall functional patchwork quilt of individual failures that once it is aligned and observed from above, behaves as a functional infrastructural element designed to safely and efficiently mobilize bodies across the city.<\/p>\n\n\n\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-f56f613f wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"wp-block-heading\">A walking tour through glitchy sidewalks<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Walking through glitch infrastructures, one needs to watch their step at any moment, there are traps everywhere. It could be a smooth tile that when is wet turns into a soapy track where an unsuspecting walker can easily slip and fall. It may be a ground energy meter without a lid, but it is also possible to face some sporadic thick slopes made to let cars go in and out of private garages as well as irregular steps randomly located around the walking infrastructure to try to level the bulging geography of Medell\u00edn\u2019s sidewalks.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-jetpack-slideshow aligncenter\" data-effect=\"slide\" style=\"--aspect-ratio:calc(600 \/ 338)\"><div class=\"wp-block-jetpack-slideshow_container swiper\"><ul class=\"wp-block-jetpack-slideshow_swiper-wrapper swiper-wrapper\"><li class=\"wp-block-jetpack-slideshow_slide swiper-slide\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"338\" alt=\"\" class=\"wp-block-jetpack-slideshow_image wp-image-239\" data-id=\"239\" data-aspect-ratio=\"600 \/ 338\" src=\"http:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/Route-A.gif\"\/><\/figure><\/li><li class=\"wp-block-jetpack-slideshow_slide swiper-slide\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"338\" alt=\"\" class=\"wp-block-jetpack-slideshow_image wp-image-240\" data-id=\"240\" data-aspect-ratio=\"600 \/ 338\" src=\"http:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/Route-B.gif\"\/><\/figure><\/li><li class=\"wp-block-jetpack-slideshow_slide swiper-slide\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"338\" alt=\"\" class=\"wp-block-jetpack-slideshow_image wp-image-241\" data-id=\"241\" data-aspect-ratio=\"600 \/ 338\" src=\"http:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/Route-C.gif\"\/><\/figure><\/li><\/ul><a class=\"wp-block-jetpack-slideshow_button-prev swiper-button-prev swiper-button-white\" role=\"button\"><\/a><a class=\"wp-block-jetpack-slideshow_button-next swiper-button-next swiper-button-white\" role=\"button\"><\/a><a aria-label=\"Pause Slideshow\" class=\"wp-block-jetpack-slideshow_button-pause\" role=\"button\"><\/a><div class=\"wp-block-jetpack-slideshow_pagination swiper-pagination swiper-pagination-white\"><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-f56f613f wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"821\" src=\"http:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/map-main-1024x821.png\" alt=\"\" class=\"wp-image-266\" srcset=\"https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/map-main-1024x821.png 1024w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/map-main-300x241.png 300w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/map-main-768x616.png 768w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/map-main-1536x1232.png 1536w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/map-main-2048x1642.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"821\" src=\"http:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/maps-routes-1024x821.png\" alt=\"\" class=\"wp-image-267\" srcset=\"https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/maps-routes-1024x821.png 1024w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/maps-routes-300x241.png 300w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/maps-routes-768x616.png 768w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/maps-routes-1536x1232.png 1536w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/maps-routes-2048x1642.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading alignwide\">Perception survey<\/h4>\n\n\n\n<p class=\"alignwide wp-block-paragraph\">Are pedestrians aware of glitches? Do they care for glitchy infrastructures? 25 people were interviewed regarding their perception and daily experiences walking over malfunctioning sidewalks in the three routes above presented. After being classified by age, and their main way of moving around their neighborhood (Figure 1), their opinion about Medell\u00edn\u2019s sidewalks was collected through a ranking exercise on a scale of one (bad) to ten (excellent). In general terms, the pedestrian perception of their neighborhood\u2019s sidewalks was positive.&nbsp;<\/p>\n\n\n\n<p class=\"alignwide wp-block-paragraph\">However, regardless of their opinion on the quality of their neighborhood\u2019s sidewalks, people were able to identify glitches as a continuous presence in their trajectories (Figure 2). This situation reinforces the idea proposed in this issue that rather than trying to repair or eliminate infrastructural glitches, people have learned how to live with them.<\/p>\n\n\n\n<div class=\"wp-block-group alignwide has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<figure class=\"wp-block-image alignwide size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1020\" height=\"642\" src=\"http:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/survey1.png\" alt=\"\" class=\"wp-image-271\" srcset=\"https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/survey1.png 1020w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/survey1-300x189.png 300w, https:\/\/tarde.info\/wp-content\/uploads\/2026\/06\/survey1-768x483.png 768w\" sizes=\"auto, (max-width: 1020px) 100vw, 1020px\" \/><figcaption class=\"wp-element-caption\">Figure 1.
