Looks great and it's convenient

Looks great but take note that you'll have to keep the laces a bit looser than on a usual boot in order for it to slip on and off easily. Might look a tad sloppy but it doesn't really bother me.

Never thought you could do a slip in boot, but you did.

As with all your products I have bought - Great job.

I like them.

had to return them to get the right size, they were tighter in the toes than my other Kiziks. I have about 10 pair and this is the only style that didn't fit perfectly out of the box, but those are pretty good odds. I really like Kizik, only shoes I wear!

Love the idea of a slip on boot

Just got back from a winter ski trip with my new Kizik boots. I absolutely LOVE the funcionality of being able to slip these on easily right after taking off my ski boots or when I need to step outside in the snow fast. They slip on and off pretty easy and are comfortable and warm, even though they are a little loose (thats ok by me, particularly after skiing!). Where I think they do fall slightly short is in the slip resistance on ice. For years I have been using half laced hiking boots for this purpose and the grip of the soles on those shoes on ice was pretty superior. These are a little slippery on ice and even on the tile floor at the coffee place. The good news is that this is a new product... they can improve the soles on these and when they do I will buy a second pair!

You might like these too.
