Nike shoes are quite small. Yes, it works as described: They are warm in the microwave, they are beautiful high cut and cuddly, you should not walk around in the shoes. Take the warm shoes and hit the coach under the covers. This has exactly 4x worked well. Even if the filling a bit slipping down because there are no separate chambers. All in all there for the 2 points. However, since the filling consists not only of flaxseed, but also from the chaff, this begins in the microwave unfortunately on to kokeln, thus "burn" already soon in the upper holes. And the seams are not for the Eweigkeit. Ever soaked flax seeds in the whole house? Conclusion: Stay away! A nice idea, but the shoes end up unfortunately after a few days in the tub!
