The Flex and Flex XP: Laser Sport Last Full rounded toe character, standard fit across forefoot and instep, with a slightly narrow heel. Added toe spring for athletic profile.
Based on personal experience the Flex has a very roomy toe box because the fabric provides more flexibility. I have four pair of Flex and two of the Flex XP. I can work all day at events standing and my feet are comfortable. I use mine primarily for work, travel and hanging out. Have never tried them on the course, I prefer a little more grip and have more golf shoes then a normal person would need. A lot of guys I play with wear them on the course and are very happy with the traction. The Flex XP is water proof and has a one year warranty where as, the Flex is not waterproof. Bottom line, I find both shoes to provide me with ample comfort in the toe areas.
