Just bought some boots

[model 70]

got them for walking the fields and working out doors aswell as camping. some "beaters" if you will. they're those pull on 10" justins that look kinda like cowboy boots but they're fir work. they have something called double comfort tecnology and i was just curious if these boots held up? how comfortable do they get after they're all broken in? they sides and top need abit of stretching.
