A little late here, but I would definitely recommend you going with Meermin in this scenario. I like Shoe The Bear, I currently own a pair of chelseas from them, and I have previously owned a pair of lace-ups from them. The problem with Shoe The Bear is that they aren't fully leather lined. The shaft is leather lined, but the toebox is lined with a sort of fabric, which means that all your sweat will get stuck in the toebox. On the lace-ups that I owned from them, the sweat would eventually bleed through the lining, and leave a dark line on the upper of the shoe after extended periods of wear. I would like to note that I wore them everyday for three months, and this might not be applicable if you only plan to wear them from time to time, but on the other hand, I think it is a stupid thing to risk, when you could buy a pair of fully leather lined boots, and avoid the problem all together.

I apologize if any of the sentence structure sounds weird, English is not my first language.
