These fit great and my son loves them! They seem good and sturdy and will hopefully last him awhile. I was impressed with how quickly they arrived. Great service!

Bought these for my daughter. They said to go 2 sizes smaller for a girl but I would say 1 1/2 as they may run a half size small. Over all she absolutely loves them and says they are very comfortable. The colors are exactly what they look like on here.

My son loves Osiris. He can browse the freshest kicks and have the hottest styles delivered right to the front door.

Osiris always fit to form. The colors are much brighter when you get them. Been rockin' Osiris since 2001.

These shoes were just as pictured. Zappos shipment is amazing. We needed these fast, and they were delivered overnight!

Great dance fitness sneaker. Fantastic support and very comfortable! They do run a little narrow so if you have wide feet, go up a half size.

Bought for Zumba class because I needed high top for ankle support. Went 1/2 size larger but it was too small. 1 full size larger was too large. Also have used twice in class and the soles are too slick and I slide when I shouldn't. The soles aren't conducive to wood floors. I have other shoes with much better soles. Since I have used I can't return so I am stuck with expensive shoes that I can't use.

Love Zappos for their fantastic return and shipping policies. Unfortunately this is the second Bloch I have ordered and had to return because it runs so darn small. I will order again hopefully third time is a charm.

Bought these for my Zumba class, since Zumba hi-tops were looking a bit clownish. I ordered two pairs, one a whole size and another half a size up based on the reviews. I wear 8.5 normally and 9.5 were an exact fit with socks. So yes, these shoes do run small. Going to return the size 9 ones. Overall, I love the look of the shoes and yes, they were pretty slippery the first two classes. Now that the bottoms have gotten a bit scuffed, they no longer slide around as much, though these are still a lot better than my regular sneakers which tended to grip the floor and make it harder to do the twists and turns in the Zumba class. These shoes also go really well with the Zumba cargos and capris, so perfect to shimmy and shake in style. ;) The sides are made of thin material, but I guess that's what makes them super light. Also, there is very little arch support, but it works fine since I am flat footed and arches make my feet hurt.

I am an instructor and I bought this for my Zumba and Bollywoord Aerobics classes. These shoes are ok for low impact workouts but be aware, they do not offer enough support. I ended up with plantar fasciitis after using these for a few months. These shoes are great for lateral movement but I strongly recommend sports insoles. They are also a pain to get on and off as they run narrower in the toe box. I had to really loosen the laces quite a bit to get my feet in, and then tighten them all the way to get the right fit. That is time consuming!
