Two advanced footwear technology models were tested in a randomized crossover design. Each session included two 5-minute trials per shoe condition at 13\u2009km\u00b7h\n \u22121<\/jats:sup>\n . Reliability and reproducibility of running economy measures were evaluated using intraclass correlation coefficients (ICCs), SEM, coefficient of variation, and smallest worthwhile change.\n \n Results<\/jats:italic>\n <\/jats:bold>\n :<\/jats:italic>\n Intrasession ICCs and coefficient of variations for oxygen cost and metabolic cost were excellent for both shoe conditions (.917 and .945; .921 and .948; \u223c1%). Intersession reliability was good (oxygen cost ICC\u2009=\u2009.819; metabolic cost ICC\u2009=\u2009.849), though coefficient of variations increased (\u223c2%). No significant differences in metabolic variables were observed between footwear models (\n P<\/jats:italic>\n \u2009\u2265\u2009.05), and high variability was observed between individuals. Day-to-day variability affected oxygen cost and metabolic cost (\n P<\/jats:italic>\n \u2009<\u2009.05), independent of shoe condition.\n \n Conclusion<\/jats:italic>\n <\/jats:bold>\n :<\/jats:italic>\n Running economy measurements are highly reliable within sessions but demonstrate moderate variability across days. Despite mechanical differences in footwear conditions, no differences were observed between the 2 models. These findings highlight the importance of multitrial, multiday, and individual testing when evaluating footwear conditions.\n <\/jats:p>","DOI":"10.1123\/ijspp.2025-0649","type":"journal-article","created":{"date-parts":[[2026,2,25]],"date-time":"2026-02-25T18:45:51Z","timestamp":1772045151000},"page":"792-799","source":"Crossref","is-referenced-by-count":0,"title":["Reliability, Reproducibility, and Individual Responses of Running Economy Measures in Different Advanced Footwear Technology Shoes"],"prefix":"10.1123","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-6344-3726","authenticated-orcid":true,"given":"Alejandro","family":"Alda-Blanco","sequence":"first","affiliation":[{"name":"Sports Training Laboratory, Faculty of Sport Sciences, University of Castilla-La Mancha, Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6327-6958","authenticated-orcid":true,"given":"Fernando","family":"Gonz\u00e1lez-Moh\u00edno","sequence":"additional","affiliation":[{"name":"Sports Training Laboratory, Faculty of Sport Sciences, University of Castilla-La Mancha, Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8642-7978","authenticated-orcid":true,"given":"Fernando","family":"Valero","sequence":"additional","affiliation":[{"name":"Sports Training Laboratory, Faculty of Sport Sciences, University of Castilla-La Mancha, Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4376-6076","authenticated-orcid":true,"given":"Sergio","family":"Rodr\u00edguez-Barbero","sequence":"additional","affiliation":[{"name":"Sports Training Laboratory, Faculty of Sport Sciences, University of Castilla-La Mancha, Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4153-5100","authenticated-orcid":true,"given":"Juan Jos\u00e9","family":"Salinero","sequence":"additional","affiliation":[{"name":"Sports Training Laboratory, Faculty of Sport Sciences, University of Castilla-La Mancha, Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"23","key":"r1","series-title":"J Sports Sci","doi-asserted-by":"publisher","first-page":"2661","DOI":"10.1080\/02640414.2023.2183103","article-title":"Impact of advanced footwear technology on elite men\u2019s in the evolution of road race performance","volume":"40","author":"Rodrigo-Carranza V","year":"2022","unstructured":"Rodrigo-Carranza V, Gonz\u00e1lez-Moh\u00edno F, Santos-Concejero J, Gonz\u00e1lez-Rav\u00e9 JM.
