Toebox can be too wide for some, Runguide System not suitable for all types of runners, Heavier

This is the type of shoe that allows you to comfortably manage your daily training, work those long runs over the weekend, to eventually lace them up on race day. Compared to the previous version of the shoe, the Puma ForeverRun NITRO 2 feels more refined but in a sense also more complex and it took me a few runs before settling in. It's heavier but offers more support than before, alongside what felt like more restriction around the inside of the forefoot meant for overpronators.
