Stretchy upper cuff can collect snow with heavy use
No stretch in Velcro closure
Reflective tape peeled off on first use
These reasonably priced booties work reasonably well. The stretchy upper cuff keeps snow out, and the fleece lining keeps paws warm, although the grip is not great when icy. They offer good protection against salt, but they are not waterproof for wet conditions. My test dogs did have trouble with the booties falling off during off-trail play, especially when snow was deep and breakable.
On trail (sidewalk or compacted snow) If you get the right size, and if you really crank down on the Velcro closure, the boots mostly stay on. They should say on reasonably well for leash walking and will protect against snowballing and salt.
Off Trail Off trail the boots can come off with vigorous play and deep snow conditions. The leather sole can also ice up or get clogged with snow, greatly reducing traction. Under heavy use, a hot dog will heat up the fabric cuff and it will start to collect snow/ice.
Comfort These boots seem very comfortable to the dog due to the stretchy elastic cuff and fleece lining. The usual high stepping can be expected when you first put them on, but the dog will get used to them quickly. Like most of the other boots, you have to crank the Velcro up VERY tightly to keep them on. Though my dog didn’t complain, I worried about long-term wear. Comfort is reduced when icing of the upper cuff begins, but I would only expect this with deep snow and high output activities.
Value This is a good value for a beefy bootie. The Muttlucks have their faults, but cost considerably less than other booties that also fall off and are slippery.
Durability The reflective strip started peeling off on my very first outing, but they otherwise stood up to some off trail use. The upper toe of the bootie is reinforced with extra nylon, which is a good thing, because that would keep them from wearing out if using them primarily on sidewalks.
