[MC-267381] Moving while sneaking is impossible with high generic.step

Give yourself some netherite boots with this command:

item replace entity @p armor.feet with minecraft:netherite_boots{display:{Name:'{"text":"Step-boots","color":"#0FF82E","italic":false}'},AttributeModifiers:[{AttributeName:"generic.step_height",Name:"generic.step_height",Amount:2.0,Operation:0,UUID:[I;1024845256,1045783364,1007170712,1113454942]}]}

You can only move while sneaking: (where x is step_height)
- when there are x+1 solid blocks below you (for x <10)
- when there are 10 solid blocks below you (for x >= 10)
