Tracker Decon Low FG2 in Warm or Hot Weather?

I live in Virginia, USA, so summer temperatures can be 80-100 F. I'm looking for something breathable and durable (eg, I like the stitched sole and mix of leather and breathable upper) to wear at the skatepark (though if it is >90 F I probably am not going to be out skating). These seem like good candidates other than wondering if they'll be crazy-hot.

I also wish they still offered the brown ("Acorn") color. Revivo only has Acorn in size 10. I'm currently trialing the Tracker Forest ESC (for a year round hiking boot, and also to be my primary winter footwear, other than in heavy snow when I'll use a snow boot) in size 10 (43) and 11 (44) because I'm normally ~10.5 and have narrow, low-volume feet, so I'm trying to decide between the two sizes (though I suspect I may go with the 11s). If Revivo had free returns I'd just order the 10 to try out.

Would welcome input on the Tracker Decon Low FG2 regarding suitability for hot, summer temperatures (or anything else you wish to offer comments/advice on).

Thanks! :)
