After doing some research, it turns out that you can indeed use football cleats for lacrosse. However, it's important to note that while they may provide similar support and traction, they may not offer the same level of comfort and flexibility that lacrosse-specific cleats do. Some players might find football cleats too heavy or restrictive for lacrosse. So, while it's not a hard no, it's definitely worth considering all the factors before making your decision. After all, comfort and performance are key in any sport.
