The objective of this randomized controlled clinical trial (RCT) with a double-blind technique and longitudinal chronology, is to evaluate and compare the effectiveness of High intensity laser therapy (HILT) in static mode versus scanning mode in the reduction of pain associated with plantar fasciitis. The main questions it seeks to answer are: * What is the comparative effectiveness between low-level laser therapy in local spot mode and sweep mode in reducing pain in patients with plantar fasciitis? * What are the optimal therapeutic parameters (session duration, frequency and power) for LLLT in both modes, maximizing pain reduction in patients with plantar fasciitis? Participants in this study will perform the following tasks: * Undergo HILT sessions or scanning mode. * Comply with the instructions on the duration and frequency of the sessions. * Record the pain levels experienced before and after each session. The investigators will compare the group this differents laser to evaluate whether there are significant differences in pain reduction effects.
