Ok but not great
"They are MUCH roomier than the G3 guide boots I bought 2 years ago, and every other pair of size 10 Simms boots I’ve bought over the last 20 years. So loose that I can’t tighten the BOA across the top of the foot without putting too much pressure on the ankle. The old Guide Boa boot tightened down much more evenly top to bottom. The G3 guide boots i bought two years ago have the gravel guard hook in the right place, finally. Yet this new version has it back in the old spot high on the tongue of the boot, totally unusable with Simms waders. They seem to well built overall, but I can’t wear them except for winter time with a thick sock. Downsizing would not leave enough room lengthwise."
