@iiaks we contacted them on FB a bit back, and they did not speak English. Didn't get the feeling that they were very active (COVID wiped out a lot of smaller gyms in Pattaya). Kongtoranee himself though is at his brother Samart's gym in Bangkok.
Right now I think the difficult is, in this equation, "fight frequently" (which may depend on your size too). It may be that Chiang Mai (and Phuket) are the most likely places. Hongthong is very popular in Chaingmai. Kru Thailand's gym is more "authentic" in terms of it being more of a kaimuay. Kru Manop's gym will give you personal attention. And maybe the new Manasak gym would be eager to devote attention to a new longer timer? I would suggest going to all the gyms you have in mind before settling onto one. Feel the vibe. Not every gym is right for every person. @samelsby
I would say it depends more on purpose, rather than speed or power. For sparring gloves, you want ones which a) protect your hand and wrist well (like all gloves), and b) protect your partner (nice soft padding, etc.).
I've also heard decent things about Leone. I have a pair of (Western-style) leather gloves from another Italian manufacturer, Montana: very good price, and seem good, at least after 6 months of use. Wouldn't mind some Thai ones, so will watch this space.
When it comes to gloves, it really depends on what you're looking for. Some folks like a lighter glove for better hand speed, while others prefer a heavier glove for more power in their strikes. As for brands, there are a ton of options out there. If you're curious about Leone gloves, I've heard good things about them too! Why don't you try a few different brands and weights until you find what works best for you?
If you're looking for a good place to start, you could check out these boxing gloves amazon as an option. They have a wide variety of options, and you can read customer reviews to get a better idea of what people like and dislike about different gloves.
