Ive upgraded from some old sworks 4 (I think) to the sworks 6. These have much bigger toe box than the old ones which was always the problem I had previously on long hot days. The 6 were lot cheaper than the new 7 (60% of price).
Some people dont like the 6 as they have higher cut around the ankle and this can be uncomfotable walking it them a lot, but I like them, so no issues for me. I like the independent dual boa’s.
