MyFishFinder.com Just like iceshanty but warmer
i think the problem is you bought slip on boots. tie on pack boots will provide much better support. mine feel like ski boots if i tie them up all of the way and you control how tight for how much support you want from them. i add kold kutters ice racing screws to my boots so i am protected any where i go and not just on lakes. i bought mine on amazon for 20$ for 250 ct in 3/8".my other tie on boots feel like ski boots too, but are not as warm. only the pack boots are the warmest of the tie on style. that i have used.
I use these for duck hunting it does provide a good bit of support...since u said that it’s hard to slide your ankle in your boot especially with an ankle brace on these might work out great for u. Put your boots on as normal then put this on and tighten er up.Linkhttp://www.cabelas.com/product/Cabelas-Boot-Straps/722084.uts?Ntk=AllProducts&searchPath=/catalog/search.cmd?form_state=searchForm&N=0&fsch=true&Ntk=AllProducts&Ntt=muck%20straps&WTz_l=Header;Search-All%20Products&x=0&y=0&Ntt=muck%20straps&WTz_l=Header;Search-All%20Products&avad=55097_ffe01f0d&WT.mc_id=al40661&Subid1=SID&subacctid=40661&subacctname=40661&adname=Custom+Link&adtype=cl&adid=NA&utm_medium=AFF&utm_source=40661&rid=12&WT.tsrc=AFF
Mickey Mouse boots are lace-up and have good ankle support, they are about the warmest boots out there, are water proof and cheap. I wear them everyday all winter long, have not found anything that works any better.
