Sorry Al, for chiming in late, somehow missed that thread. I had and still have both, Alps Tech 7's and Leatt 5.5 Flexlock. I also have Gaerne SG 10's and I had Gaerne SG 12's. The SG 12's are the heaviest but also the safest boots ever. I had a bike falling on my left ankle and the tip of the brake pedal punched through the boot. With a Tech7.... well I don't want to imagine.
However, my personal opinion about the Tech 7:
pros: comfiest boot ever, good buckles, light. Cons: say the words "water", "wet" or "rain" and your feet will be wet immediately, worst boot in this respect but the "Drystar" model will be better in this respect. The buckle on the instep looks weird and tends to come undone..
I had about 10 to 12 rides with the Leatt so far and I am pretty happy. They have sure better protection than the Tech 7's keep water out longer, have good buckles and an ingenious velcro closure system. The buckles are a pain to close when dirty and need more attention, in other words you need to clean them thoroughly after every ride. If dirt remains under the pivot point you need a massive force to close them.
They make weird noises when walking and the two little plastic parts that come with them to adjust the angle of the bootleg are crap in my opinion. Tried both, felt no real difference, so leave them alone as the tiny screws are secured with Loctite and can be a pain to get out.
It is strange but I feel the soles are thicker and I stand higher on the pegs but in reality they are not. My mate had the same impression but maybe it is due to a different cushion.
I bought them because they are really comfy, I got them for 289.- instead of 399.- and they do not look to Star Wars like. To reduce the strange noises they make I always spray them with lots of silicone spray.
