Do you think you can get 400 wears out of the artista shoes before needing to resole them?Oh, quite hard to say, some periods very often at very hard use, long days long walks sometimes bad weather etc (like during trunk show periods with lots of travels and they have been one of few shoes brought), some periods less and in more kind environments. Maybe once a week if calculated some average for the whole year.
Ok, yeah could be that you were a bit unlucky, even if I find TLB quite consistent in general (specially compared to many other Spanish factories) there can be cases with variations. One of the strongest points in general for British manufacturers is good consistency, but you get much simpler-made shoes. The mentioned C&J Benchgrade are for example very simple construction-wise, with square waists and fully square sole edges, heels cut far from the uppers, open channel soles, and that at an (as mentioned above) higher price point then even Artista. If that's something that one don't care much about, it of course C&J could still be the better choice.
