(I bet I didn't spell that right.). These overshoes are somewhat cumbersome but they work great! They are way easier to put on than the galoshes I remember from my kid days. They seem very sturdy and the studs in the bottom are helpful for traction. They have fit over my tennis shoes, flat shoes with thick soles and a light pair of hiking boots. The velcro zip up is great and the strap that goes over your arch is a pull strap with velcro so it's adjustable. A hint: loosen it all the way, get into the over shoe THAN tighten it up. The coolest part is in the bottom of each shoe is LEFT or RIGHT so you know which foot it goes on! Super idea! I think they might leak a bit BUT the reason I bought them was for walking the dogs on slippery city streets and for that they are great!
