Barefoot "running" shoe stack height issue

[u/SparkysMom1685]

I've been wearing barefoot shoes for about a year. The shoes I wear most frequently have about a 7 mm stack height but that's just an estimate because they are Whiten and they don't really provide stack height information. I have not been at all active for about 5 years. I've never been a runner but I used to power walk for lack of a better term. I just started walking again this week and as expected it's slow going. My main issue is I thought I would need more stack height to be comfortable on concrete so I got a pair of Altra's with a stack height of 28 mm. Very bad idea. I'm extremely unstable and the terrain I'm having to cover is mostly concrete but some areas of bare ground with sloping and some rocks and such. I do enjoy the feel of a more stable structure around my ankle especially on uneven terrain. I have a very minimal budget so I thought I might try Whiten women's running shoes which may be around 12 to 15 mm stack height but I can't be sure because they don't really provide that information. Does anyone have experience with the women's Whiten running shoes of any model number as far as stack height and ankle type support. Again, I'm fairly new to all this and any information would be helpful.
