Question: Male, wear size 81/2 shoe. What size should I order?
Document: I bought a pair of white ones at size 43 and they were a little small (I wear size 10W or 10.5) because these shoes are thin for the length, then bought another two pair of 44s, and when they wear out, I'll buy two more pair. I've gotten many complements on the look of the shoe as well.
This was my third pair of Feiyues I purchased. You cannot find a better shoe for the price and comfort. Though, they have a relatively short lifespan (anywhere between 6-12 months depending on how you wear them out), they get put to pretty good use and I can't imagine myself wearing anything else on the street. Light, comfortable, like a second a skin.
While these are great for working out, my feet start to rebel after a few hours of ordinary wear. The thin sole lets you really feel the surface on which you are stepping, but there is a lack of support if you are used to wearing running shoes. Given that they are available delivered for under $25.00, they are an excellent Kung Fu work out shoe. There are certainly other more expensive shoes built for the purpose but some very advanced practitioners of the art chose to wear these.
Looks, of course, can be deceiving. When I noticed some of my brothers and sisters in Kung Fu wearing these low top shoes I was curious but thought that they were probably just a trendy mediocre Chinese knock off of Chuck Taylor's classic All Star basket ball shoe. GO ahead . . . call me cynical.What I missed was that these shoes are very light and significantly enhance one's ability to kick.
I don't use them for martial arts, but around the house almost like slippers which they work well for. They aren't designed for walking around town in, you can, but you'll wear out the soles rather quickly. Comfortable.
I prefer black because its Kung Fu and because the white shoes really do show the dirt but that is just me.Evidently, the Shaolin Monks wear these which tells me that they are more than adequate for the purpose and yet are a no frills product. I would recommend that these shoes are certainly worth a try.
I got these shoes to wear in a boxing ring when I box or grapple and they are pretty amazing. They have the best qualities of both wrestling and boxing shoes. (grip and flexibility). Obviously if you were really into boxing you would want more ankle support but for just sparring and mitt work, they are great
I thought they were the best shoes, that I hve seen so far. I saw a show with Monks wearing the shoes thank you.
I had heard about these from a friend what seemed like an eternity ago, but they were not readily available back then. Then I find them on Amazon, for a great price? Had to give them another look.I will start off and say that they are easily as comfortable as any slippers I've had and they even look good enough to go out in.
Also there is no arch support at all, nor any ankle support, sometimes I have to use arch support insoles but only when my feet are hurting from long runs.Want to add: I hurt myself doing a precision, because I completely forgot about the lack of any cushioning, landed on the edge, and bruised my heel bone.
Answer: yes
